Former Liverpool and Germany midfielder Didi Hamann told InstantWithdrawalBettingSites.com: "I think Borussia Dortmund has been a great place for Jamie Gittens, he played a huge role and scored goals and got assists, but that stopped when Niko Kovac came in.
"Chelsea will be fully aware of that, the player has made it clear he wants to leave but he is under contract, I would say that Dortmund are not in the strongest position because the manager wants hardworking players and Gittens isn’t that type of player.
"I think he will leave Dortmund but they won’t get the money they want. Chelsea have an abundance of players, I think he could make a real difference at Manchester United, he is young but he has stood out and I think that might be the player for them to chase."
