After watching his Chelsea side lose a Premier League game for only the fifth time under his stewardship, Thomas Tuchel was quick to insist that focusing on small details could solve our issues and that the big picture should not be doubted.

The Blues have now won two of our past five league outings and slipped to third in the table behind Manchester City and Liverpool following a 3-2 reverse at West Ham on Saturday lunchtime. Yet with a hectic fixture schedule on the horizon, including the traditionally manic festive season, time may be limited to find solutions to some of the team’s creeping problems.

We head to Russia this week for the final Champions League group game in St Petersburg before hosting Leeds United next weekend, and our next midweek without a fixture is not due until the new year. However, Tuchel believes he knows what is required to deliver a quick fix.

‘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.’
