Chelsea boss, Thomas Tuchel says he made one big mistake during his side’s 2-0 win over Lille in the Champions League round of sixteen tie at Stamford Bridge on Tuesday.
The German blamed himself for the injury sustained by midfielder, Mateo Kovacic, admitting he should have brought the Croatian off earlier after he was forced off six minutes into the second half with what appeared to be an injury.
Chelsea will now wait anxiously to see whether he will be fit for Sunday’s Carabao Cup final against Liverpool.
“I don’t know. “I should have substituted Kova at half-time so we could have saved one more change,” Tuchel told reporters after the game.
Kai Havertz and Christian Pulisic scored for Chelsea against the French champions as Tuchel dropped Romelu Lukaku to the bench.
