Owen Coyle believes Jack Wilshere could return to haunt Bolton on Saturday at the Emirates Stadium.
The 18-year-old midfielder had a successful loan spell with Coyle's side in the second half of last season.
Such was the improvement in Wilshere's game he has featured in Arsenal's first three Barclays Premier League matches.
Not only that he was called into the England senior squad for the friendly against Hungary. Wilshere was back playing for the Under-21 side in midweek following his arrest and subsequent bail in the wake of a late-night fracas in London.
Bolton boss Coyle said: "Jack is a very talented player. He is such a gifted lad and has matured no end. He came to us as a boy and went back to Arsenal as a man. He showed that by playing in the Arsenal first team and by turning out for England at full international level. There is no doubt he is going to have a glittering career.
"He knows the way we work and he has a lot of friends here. But during the match we will try to nullify the threat he poses."
