Chelsea boss Mauricio Pochettino was delighted with their FA Cup win against Preston.

Chelsea won 4-0 thanks to goals from Armando Broja, Thiago Silva, Raheem Sterling and Enzo Fernández.

Pochettino said: "Yes a very good win. The first half I was a little disappointed. We started so sloppy. I told the players at half-time we needed to increase the energy and match that of Preston.

"The second half was a completely different game. We dominated, created chances and deserved victory. We showed a lack of desire in the first half and we were talking too much about their energy. They were better than us in this area. I was really disappointed but after we increased our level we started to play and deserved to win.

"We are a young team that needs to be build through results but also performances to get confidence. It will be tough but we are looking forward to the semi-final.

"I think it's a massive responsibility because we are Chelsea. Of course I am enjoying it. That is the pressure. I'm a coach that loves to win and be competitive but at the same time we need to give time to the young kids so they can improve and mature. We need to find a balance. It's a matter of time before the team will perform because we have the quality. We have a group and team to be better."
