Christan Pulisic was glad his goal could 'calm' Chelsea against Lille on Wednesday.

The French side went one goal down on aggregate thanks to Burak Yilmaz's first-half penalty.

But Pulisic restored the two-goal buffer on the stroke of half-time, with Chelsea eventually prevailing to the Champions League quarter-finals.

"It was a really good goal we got right before half-time to calm us down a bit and in the end we should be proud," he said.

"It's not easy to get a result here and we did that. Going into half-time 1-0 down would have been tough so it was definitely helpful.

"We know they're a good team and coming here is never easy. In the first half they were strong and there was a good atmosphere in the stadium. They put a lot of pressure on us right away.

"They gave us a lot of trouble and then with the handball penalty they were back in the game. We made a few changes and were able to calm the game down a bit with some possession but the goal we scored before half-time was really important because it restored confidence."
