#2 Carl Jenkinson
Like Rob Holding, Carl Jenkinson was another youth prospect that Arsenal held closely to their chests, eager to see him fulfil his potential. But that day never came, and after failed loan spells with West Ham and Birmingham, Jenkinson is merely biding his time now until his release.
Jenkinson's contract is set to expire by the summer, but in case Arsenal decides to trigger a one-year extension clause, he's been added to this list as an obvious choice to be sold. They could still get around £5 million for the 27-year-old if they were to sell him, which is better than nothing.
He will likely end up at a championship side, but still not as a permanent fixture in the first team squad; he's more likely to be a backup option, especially for clubs in the top half.
