Yet the biggest winner could be a player who is already part of the first team, and one who has already worn the captain's armband, Liam Cooper.

Cooper is one of the better signings of the Cellino era at Leeds, snapped up from Chesterfield in 2014.
He earned the captaincy in his first season at Leeds, before the addition of senior defender Sol Bamba, a clear leader on and off the pitch by nature, saw him handed the armband instead on a permanent basis last summer.
Cooper is just 24, and was given his first Scotland international cap earlier this year. While he did not get on the pitch to make his debut, the call-up was vindication that he is playing well enough to get noticed, even with Leeds display indifferent form.
Last season the centre back pairings at Leeds proved to be a juggling act for bosses Uwe Rosler and Steve Evans, as they attempted to fit two players into three spots, between Cooper, Bamba and Bellusci.
While not flashy by any means, Cooper was the least error prone of the trio, and ended the season as he began it, in the starting line up.

Under Monk, Cooper's game could potentially reach the next level, by learning from the former centre-back.
The head coach made more than 300 professional appearances, and played in the Premier League late into his career with Swansea City.
Cooper is talented enough, and still young enough, to take in his advice and adapt his game in areas his manager recommends, and become an even more important part of the Leeds team.
