Tuchel has won 40 of his initial 67 Chelsea games and already won two trophies, and reached three finals in his time at the club.
Speaking to The Sun, Joe Cole has lauded the job the Bavarian has done thus far.
‘Barring Mourinho’s first spell, he has had the biggest impact of anyone managing Chelsea. He is universally loved and respected by everyone at the training ground,’ Cole said.
‘Chelsea is a very successful club but it can be turbulent. A lot of managers can buckle under that pressure — even experienced ones.
‘But the way the players have responded to him has been great. You couldn’t have envisaged a better first year in charge. Thomas is a very smart man who recognised the quality players straight away.
‘But he also recognised the soul and style of the club; he understands the history of the club. He gets it,’ Cole added.
‘When I went to Cobham to interview a few players, he came over for a chat and is an impressive guy. As an ex-player, sometimes you can go into a club and it can be uncomfortable with certain managers.
‘He was very welcoming. It says a lot for his emotional intelligence. Everyone I speak to at the club feels embraced by him. That takes a character who can do that.’
