Chelsea boss Thomas Tuchel says his side will have to “fight for every centimetre” when they host Real Madrid in their Champions League semi-final second leg next week.
The Blues secured a potentially important away goal as they drew 1-1 in Madrid in the first leg.
But Tuchel knows there is plenty more work to do if they are to reach a first final since winning in 2012.
“Even if we had won here, everything is possible,” he said.
“It’s half-time and we’ll have to fight for every centimetre and every advantage that we want to have and we need to fight and deserve it.”Christian Pulisic had put Chelsea ahead on Tuesday before Karim Benzema equalised in a thrilling first half.
The second period failed to live up to the excitement of the first, and Tuchel felt his side should have made more of their superiority in the early stages of the game.
“I have a feeling we should have won the first half and that we deserved to win the first half,” he added.
“We could have perhaps decided this game in the first half an hour when we were playing so strong.”
