I'm probably in the minority here but I wouldnt mind this. Bentley isnt a player i'd personally aim for but he does have qualities.
Petrov has had his day IMO, he was one of my favourite players under Sven, but he isnt as good as what we have now. He's a great player to have in the squad but from his attitude this pre season, he sees himself above that. Its a little bit Elano-esque for me. He's 30 now, isnt going to get better and had a bad injury to have at his age last season.
Its a shame, I would have liked to sign him a few years earlier when we were tossing about with Riera and Musampa, though I suspect we would have been a backward step for him at that time.
Petrov's biggest strength is his pace, personally I feel he lost a yard last season when he did play, which is natural as he is 31 soon and will only lose another yard or two. Id prefer to keep him as a squad player but he wants first team football.
Bentley - played his best football under Hughes. Doesnt have the pace of Petrov but has a better delivery. We dont really have a right sided player with a very good crossing ability, he would provide that and would be good service for Santa Cruz and Adebayor. RSC wouldnt have scored half as many for BBurn without him. He may be happier being a squad player then Petrov would be.
I dont like the guy personally, I dont like Bellamy personally, but he's a good player that does well for us and is committed, which is all I want to see from players. If Bentley does the same and gets 10 assists a season, im happy with that.
