AC Milan striker Antonio Cassano admits he is already thinking about retirement. Cassano scored a brace in victory over Northern Ireland.

"I've been a clown since birth, I'm not capable of being serious! This morning I told Gigi Buffon I'm one of the oldest in the side, but only have 25 caps.

"I keep coming in and out, but in three or four years I'll stop with the Nazionale. I think I'll play football for only that time, have a good Euros and a good World Cup, then at the age of 33 call it a day so I can enjoy my family.

"I want to be gone when I'm in good shape, not when I'm struggling. Will that be it for me and football? Of course, playing is the only thing I know how to do! I can't talk, I can't do anything.

"For years I have been stressed out, as all I have to do is scratch my nose and I get turned into a problem. Football has been the most wonderful thing in the world for me, but I am a little tired, so I'll give another three and a half years, then that'll do."

When told he hadn't won much in his career, Cassano took responsibility for his many mistakes.

"Sport gives you back what you put into it. I didn't put enough in, so I didn't get much out. If Buffon won 10 times as much as me, it's because he was the absolute number one in his role. I was one of many.

"Next year I'll be 30. I would like another three years at the top and then that's it. Things are becoming routine for me and I'm no good with that kind of situation."
