"They may have a problem when two or three of their key players get injured. I don't know if it is an advantage. We are happy at the moment and confident that we can win it.
"The most important thing is that we have to win every game and that is all we can do. We must concentrate on our own game and our performance and not compare ourselves with what Man United are doing.
"Christmas is coming and maybe next month the gap might have changed. The Champions League and FA Cup are starting again next year so all the teams will have so many games.
"Everything can change if Arsenal keep winning and both us and Man United drop points but we have to keep winning to keep that gap below us while trying to catch United.
"I expected a bit more of Arsenal this season, but they have lost quite a lot of games and I am a bit surprised. I also expected Liverpool to be closer to us."
