Chelsea boss Liam Rosenior, speaking to BBC Sport: "I was delighted with the players' application and attitude in the first half. It was a difficult game. We've had some good 90 minutes. Obviously, you want every minute of every game to be perfect. There is a lot of things we can improve, but in terms of our start together, I am delighted with it.
"Pedro Neto has been outstanding. He works so hard and he has so much quality. I am delighted to see him get the goals he got. Everyone worked really, really hard for each other.
"The most pleasing aspect was the mentality. They were a credit to the club. It was a really strong performance in terms of the mental application you need to be successful."
Enjoyed coming back to former club Hull? "I had over 20 of my family here. This club means a lot, not just to me but also my family, for many reasons. I really appreciate the reception I got from the club and it was nice to get a good reception from both sets of fans."
Chelsea striker Liam Delap, speaking to TNT Sports: "We came here with one task and that was to win. We showed we can battle and also play some good football, so we are happy.
"Pedro Neto is an incredible player. He is playing in a position he is not even used to but he showed his quality."
On the chance he had in the first half: "I swear on my life, I almost ran off. I thought it went in and was waiting for the referee to blow his whistle. It was silly from me, but I thought it was in."
