Former West Ham midfielder Robbie Slater feels Daniel Arzani has blundered joining Celtic.
Arzani is on-loan at Celtic from Manchester City, but is yet to appear for the Hoops.
Slater said: “It was an obvious error to take him there.
"After doing what he did at the World Cup he needed to go somewhere and play regularly.
“Clearly, Brendan Rodgers won't be starting him any time soon.
“Something's gone wrong – very, very wrong there."
