The Blues boss has not said that he doesn't want to sell Gronkjaer so it looks like he may be ready to release the Danish international winger when the transfer window opens in January.
Gronkjaer has failed to win over the Blues fans since his summer signing from Chelsea and was dropped to the bench for Blues' last home game against Norwich City last weekend.
Athletico Madrid appear to be interested in signing Gronkjaer if reports this week are true.
