He has not washed it, he has spilled beer on it and he is not denying he has slept in it.
But Richard Wilson says he will give Andy Boyens back the shirt the former Dunedin defender wore in the All Whites' 1-0 win over Bahrain last Saturday.
Wilson, who lives in Christchurch but is shifting back to Dunedin, said he could not believe it when he was given the shirt by Boyens shortly after the All Whites' victory last Saturday night.
Who ended up with the shirt had been something of a mystery after Boyens gave it away straight after the final whistle.
Wilson (39), who was close by when the All Whites were saluting the fans straight after the game, was the lucky man.
Wilson coached Boyens at Fletcher Cup level, when Boyens was 16 and still at Kavanagh College.
"He wanted to play midfield but I said to him, `No way.
"With your pace and skill you have to go into the centre of defence,"' Wilson said.
"And as soon as he went back there he looked a natural."
Wilson, who only coached at Dunedin Technical for a couple of years before moving north, followed Boyens' career as he went further up the grades, and got to meet up again with him, albeit briefly, on Saturday night.
"I was with a group of guys up there and of the 11 of us, I was the only one who could not get an All Whites shirt.
"I spent most of Saturday looking around and trying to find one but had no luck.
"All I could find was this $19.95 New Zealand flag."
Wilson and his mates went to the ground and were seated close by the All Whites dug-out.
"I told Andy to come and get my flag at the end of the game.
"So at the end he took the flag and took his shirt off and gave it to me.
"It was a complete surprise.
"I had a great night, everyone looking at my shirt.
"One guy offered me $2000 for it.
"It's got a whisky stain and a beer stain on it now.
"Then I pulled some drunk punter out of the gutter about 3am and got a blood stain on it."
It also has a grass stain on it, as Boyens got on to the field in the last three minutes as the All Whites held on for a famous win.
Wilson said he wanted to give the shirt back to Boyens and hoped to do it in person when Boyens returns to Dunedin for Christmas.
"I would never keep it, but want to give it back to him in person so I can buy him a beer."
