Barkley was given a number of ultimatums towards the end of last season but did not sign any new contract, and Koeman says that no new deal will now be offered.
Koeman said, “I found out at the end of the season that he wanted a new challenge.
“I need to respect that.
“It is really clear;I am looking to other players, and not Ross, with all respect. It is his decision.”
He confirmed that Barkley will train with the first team once he returns to fitness as he still has a year remaining on his contract, but confirmed that he would not be in his immediate plans.
He added, “He has one more year of contract and we work with respectful people and if he comes back after his injury then he will be part of the first team sessions.”
