Chelsea midfielder Cesc Fabregas was delighted with victory over West Brom.
Fabregas came off the bench to help secure the 1-0 win.
“It was vital,” said Fabregas. “We’ve been training all week on the mental aspect, especially for games like this. I don’t think we’ve faced enough teams like this recently, they have a very deep block and we knew it would be difficult to create chances.
“They had a plan and they played it very well, but thanks to Diego once again we have three points, it’s fantastic.”
