“We have a number of options in attack and real competition for places which is what every manager wants.
“We are excited about Anthony coming here and I think he will prove to be a real asset.”
He last featured for Ronny Deila’s team in the 3-1 win over Dundee United in August and was forced to apologise after sending an ill-judged tweet when he was left in the stands at Inverness in November.
He said: “It’s important for everybody he finds himself, gets some good performances and can then perform for Celtic again.
“Does he still have a Celtic future? Yeah, everybody has that.
“He has a contract with the club and Stokesy knows the things he has to take care of.
“Hopefully, he will get a good run of games, score some goals and get back in good confidence and the best shape he can be in.”
