That scoreline, with the goals an own-goal and a late strike from Hakim Ziyech, also means the Blues have equalled the club record for consecutive clean sheets, matching the seven in row set in our very first season in 1905/06 and equalled in 2003/04 and twice in 2005/06.
However, on this occasion, Tuchel feels his team were fortunate to register another shut-out as Sheffield United came into the game strongly in the second half, although there are understandable reasons why the Blues were not in full control.
‘I could feel a bit after the game against Atletico [which Chelsea won on Wednesday] that we were a bit tired and I could feel that it was a huge effort also mentally against Atletico,’ Tuchel revealed.
‘After that it was a big relief and then there were a lot of team changes made by me. Then you have players leaving right now for international duty so there are a lot of things to organise, many unclear situations, so there was a moment yesterday when we prepared the match and again today where I did not feel 100 per cent comfortable or sure we could continue on the same level.
