"We have the right mentality that you need for fighting against the top sides and to win and stay at the top of the table and remain unbeaten is a massive message.
"To come here with the mentality and the character the players showed today for winning was a big boost for the rest of the season. We have belief, quality and character.
"It's enough for being at the top of the table and we will now start thinking about Portsmouth and another three points.
"We have showed good qualities today that we can come to Chelsea and win the game. Against a very offensive team I felt we controlled the game.
"We had other chances and we didn't just sit back and defend the 1-0 lead. We kept the attacking mentality and tried to get the second goal.
"The team worked so hard and the players knew what to do. We had more space going forward in the second half because they were pushing more players forward. We defended really well and they didn't have too many opportunities.
"Credit to my players who were really good. The key for me is if you have players with quality who work hard then you know you will have a winning team.
"Our supporters were behind us as always and for them, for us and everyone in the club it was a fantastic day."
