Mourinho: I never know if Costa is fit to play or not!

The striker was forced off against Barcelona and subsequently missed losses to Arsenal and Fiorentina, with the manager admitting even muscle scans are not conclusive

Jose Mourinho has admitted that Diego Costa’s continual hamstring problems are becoming a concern for Chelsea.

The striker missed Sunday’s Community Shield loss to Arsenal before sitting out Wednesday’s home defeat to Fiorentina as the Premier League champions pre-season preparations ended with a whimper.

Costa made just seven league outings from February onwards after suffering niggling setbacks to a long-standing injury, but Mourinho has revealed even scans do not show any damage.

“Costa is not ready. It is not a good feeling for him, it is not a good feeling for me,” Mourinho told reporters. “I have to be honest and say that it is a bit of a concern. A player that didn’t finish the season and [then] doesn’t start the season obviously doesn’t make me happy.

“The boy is trying hard but he has a problem against Barcelona [last Tuesday]. The scans show there is no injury so next day he trains, but the next day he is not comfortable. Then, 24 hours before the [Community Shield], we don’t know if he plays or doesn’t play.

Mourinho added: “I won’t risk my reputation again. You asked me before last weekend and I told you he was ready to play. He wasn’t. I don’t know. I don’t risk saying yes, and I don’t risk saying no. On Friday at the next press conference I think I will tell you again that I don’t know.”

Chelsea host Swansea City to Stamford Bridge on Saturday as they start the defence of their league crown, with Radamel Falcao or Loic Remy expected to lead the attack.

Deadpan Mourinho on latest Chelsea defeat: I prefer to score 10 goals than noneā€¦!

The Blues boss referred to Wednesday’s home defeat to Fiorentina as a “good training session” and insists the real work starts against Swansea in the Blues’ Premier League opener

Chelsea manager Jose Mourinho gave a deadpan response when asked about his side’s defeat to Fiorentina on Wednesday, insisting he would obviously rather win 5-0 or score 10 goals.

The result at Stamford Bridge in the International Champions Cup meant that the Blues have failed to win a single game during pre-season, losing three, including the Community Shield defeat to Arsenal, and drawing two.

Mourinho, though, is adamant that the game was a useful training exercise, suggesting that he is unconcerned about his side’s poor recent form ahead of the big kick-off in the Premier League on Saturday.

“It was a good training session,” he told Sky Sports. “A good experience for the young boys to have a better feeling of first-team football. For the others, they needed minutes. They had minutes.

“The ones that didn’t play on Sunday they had 55, 60 minutes. The ones that played on Sunday 30, 35. Which is what we had organised.

“I prefer to win 5-0 than lose 1-0. I prefer to score 10 goals instead of no goals, that’s obvious. But the real one starts on Saturday.”

Costa: Neymar texted me about Bayern

The winger says the Selecao skipper sent him a message on Whatsapp congratulating him on his €30 million transfer to Bavaria from Shakhtar Donetsk

Douglas Costa has revealed Brazil team-mate Neymar congratulated him on his move to Bayern Munich via text and told him the Bundesliga champions were the perfect club for him.

Costa joined the Bavarians from Shakhtar Donetsk on July 1 for €30 million, with the former Gremio ace signing a five-year contract with Pep Guardiola’s side.

The winger turned down Manchester United and Chelsea before moving to Ukraine in 2010, but says he now feels capable of making the grade at a top European club.

“The Bundesliga is well respected in Brazil, especially after the World Cup,” Costa told Bild, alluding to the Selecao’s 7-1 semi-final defeat at last year’s World Cup.

“Neymar Whatsapped me just after the transfer was announced: ‘Congratulations, Bayern are a top club; that’s perfect for you.

“I’m happy for you, hopefully we meet in the Champions League!’

“I would have had no place [at Chelsea or United in 2010]. I didn’t want to watch the stars; they had lots of better players than me during that time.

“I knew that if I wanted to make the breakthrough in Europe, I needed a club to develop at first.”

Costa never scored more than six league goals during his time in Ukraine but acknowledges that much more will be expected of him at the Allianz Arena from an offensive perspective.

“At Shakthar, I also had some defensive roles, for example, as a right-back,” he added.

“But Pep is not planning on using me as a defender. I will be playing near the opposition box.

“So, six goals per season will definitely not be enough for me at Bayern.”

Rahman has agreed Chelsea terms – agent

The 21-year-old left-back is keen to push through a switch to the Premier League and his representative, Sascha Empacher, says that the Blues just have to set terms with Augsburg

Augsburg defender Baba Rahman is ready to join Chelsea, says his agent, with just a fee left to agree between the two clubs.

After the sale of Filipe Luis back to Atletico Madrid, the Blues are in the market for a left-back and have targeted the Ghana international.

With Rahman keen to get the deal over the line, his agent, Sascha Empacher, says that personal terms are all set as the teams continue to negotiate.

He told Sport Bild: “It is only the clubs that have to find an agreement. We on our side are agreed.”

Empacher had earlier confirmed on Friday that Chelsea had “made an attractive offer” to the 21-year-old.

Augsburg appeared to line up a replacement for Rahman on Tuesday, signing left-back Philipp Max from Karlsruhe.

Mourinho: My relationship with Abramovich is much improved

The Portuguese was sacked by the club’s owner in 2007 despite winning two Premier League title, but returned to Stamford Bridge in 2013 and went on to win the league last season

Jose Mourinho has revealed his previous differences with Chelsea owner Roman Abramovich are long behind him and they now enjoy a harmonious relationship.

The Chelsea boss was sacked by Abramovich in 2007 despite claiming two titles in his first three seasons at Stamford Bridge, Mourinho departing after an indifferent start to the 2007-08.

Trophy-laden spells with Inter and Real Madrid followed before the 52-year-old was lured back to the Premier League by Chelsea in 2013, Mourinho winning his third English title in his second campaign back at the club.

As Chelsea prepare to begin their latest title defence against Swansea City this weekend, Mourinho is delighted with his working environment.

“In my first period, my personal relationship [with Abramovich] was very good [but] professionally we had some interferences and a bit of a disagreement with some ideas,” he told Sky Sports News.

“In this moment we don’t have this problem. When I left Real Madrid to come here, Mr Abramovich asked me to fight for titles.

“In my first season we were almost there, in my second season we did it and in my third season if you are close, you can always do it.”
