Chelsea boss Thomas Tuchel has admitted the blame as his side lost 3-2 to West Ham at London Stadium on Saturday
‘It’s details and you can always solve the details,’ said the boss. ‘There is no need to question the big picture and no need for major doubts.
‘In my opinion, it’s obvious why we did not have the result that we wanted against Man United and West Ham so it’s about details. That’s why I think we can sort it out straightaway.
‘Nobody wants to make mistakes but it won’t help if we just say “hey, don’t make mistakes anymore.” We have to go through it and we need to be better in decision-making in crucial moments of matches to be able to have clean sheets or concede a maximum of one.’
The Chelsea head coach also claimed Romelu Lukaku, who was introduced at half-time at the London Stadium for the stricken Kai Havertz, should not have been used as the Belgian remains short of the requisite match fitness to compete for long periods in the Premier League.
‘It’s my fault,’ he added. ‘I don’t think he is ready for 45 minutes physically but still we decided to bring him on for his height because we lost Kai.
‘Kai had a crucial role in defending set-pieces, which is a huge threat from West Ham, so this is on me. I took the decision so it’s my responsibility.’
