Aston Villa manager Tim Sherwood has revealed in-demand defender Ron Vlaar has told him he wants to stay at the club.
Arsenal manager Arsene Wenger believes squad size is crucial ahead of a potentially busy summer of transfer activity.
Since taking charge at the Reebok, the Scot has overseen an unbeaten four-game run which has seen a victory against Cardiff followed by three draws.
But with the Trotters seven points off the play-off pace, the Wanderers boss has said he will need to make bold decisions if the Lancashire club are to make an immediate return to the Barclays Premier League.
He told BBC Radio Manchester: "It's no good having 40 players and 35 of them are no good. During the week, I'm understanding who wants to push on with their careers."
"The options are good to have, but you want the options that can win you games. We've got to look at the squad and see if it's the squad depth that we need, or whether it's the quality."
