Neil Lennon believes Tony Watt is ready to play for the Celtic first team now "the penny has dropped".
The Scotland Under-21 international has been loaned to Belgian outfit Lierse and has impressed his manager, scoring eight goals in 13 appearances.
Lennon feels that Watt has now developed enough to return to Celtic and believes he can challenge for a place when he returns in the summer.
The Celtic boss told the Daily Record: "Tony will be back in my plans.
"The reason for sending him away was to get games under his belt. He's playing well and scoring goals, but he's our player and he's coming back.
"He's seeing life from a different perspective now and the move has done him the world of good.
"He was little bit homesick but once he got over that he was OK.
"I thought a year away would let him realise what he had here and hopefully the penny has dropped."
