Chelsea boss Thomas Tuchel says his side will have to “fight for every centimeter” 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 within the first leg.
But Tuchel knows there’s plenty more work to try to do if they’re to succeed in a primary final since winning in 2012.
“Even if we had won here, everything is possible,” he said.
“It’s half-time and that we ‘ll get to fight for each centimeter and each advantage that we would like to possess and we need to fight and deserve it.”
Christian Pulisic had put Chelsea ahead on Tuesday before Karim Benzema equalized in a thrilling first half.
The playing period did not live up to the thrill of the primary, and Tuchel felt his side should have made more of their superiority within the early stages of the game.
“I have a sense we should always have won the primary half which we deserved to win the primary half,” he added.
“We could have perhaps decided this game in the first half an hour when we were playing so strong.”
Timo Werner did not take an excellent chance to attain before Pulisic’s opener as his shot from four yards out was saved.
Werner, who has 11 goals altogether competitions for Chelsea this season, scored the winner against West Ham within the Premier League at the weekend but also missed an enormous chance in that game.
“He missed an enormous one at West Ham and he missed an enormous one here but it’s nothing to cry about,” Tuchel said.
“This is that the neatest thing about sport, nobody cares tomorrow. He is maybe angry.”
Real Madrid is 13-time winners of the Champions League but boss Zinedine Zidane accepts his side will have to work hard if they are to keep alive their chances of a 14th title.
The Spanish giants visit Stamford Bridge for the second leg on Wednesday, 5 May (20:00 BST).
“We’re alive and we’re going to the second leg with the idea of winning,” said Zidane. “In general, we’re happy.
“We know they’re good in the opposition half, that they’re a competitive side and they don’t concede many. They’re in the semis for a reason.”
