He said: "Arsenal are unique. There is no-one else in the world that plays their particular style.
"Chelsea offer you much more of an orthodox threat in set-up and build-up and have shown they can grind out results very well. They are not averse to a 1-0 win and doing just enough to get that.
"They are past masters of it like Manchester United have been. And a win is a win is a win. When it comes to the end of the season points are tallied up for the title.
"With Arsenal at any given time any four players could be beyond the front man with (Tomas) Rosicky and (Cesc) Fabregas all bombing on and every now and then (Gael) Clichy will go past (Emmanuel) Adebayor.
"At one stage when we were playing Arsenal this season the back four weren't marking anyone because they had all dropped deep. Then all of a sudden they all ran forward and it was like the Red Arrows.
