Chelsea boss Thomas Tuchel has reflected on the dark place a defeat to Manchester United put him in during his time in charge of Paris St Germain.
The German will face a familiar foe in the shape of Ole Gunnar Solskjaer at Stamford Bridge on Sunday in what will be his fifth meeting with the former Red Devils forward in just over two years.
It remains honours even between Tuchel and the Norwegian with two wins apiece but one particular loss in the Champions League proved tough for the 47-year-old to swallow.
"Winning drives this club and winning drives this dressing room, so we are all competitors and we are all out there to win and this is the challenge.
"Everything else in the first moment is hard to accept. Sometimes easier, sometimes worse but I would love to turn it around.
"We love the competition and we love to win and we love a good fight for it and this is what we will hopefully get on Sunday."
