Celtic attacking midfielder Kris Commons has admitted to the club's official site that replacing Gary Hooper has been difficult.
Hooper was Celtic's main attacking threat during his time at the club prior to his move to Norwich City and finding someone as prolific as the Scotland international has been impossible for the Bhoys to date.
Although Celtic have tried out a number of different options up front since Hooper's departure, none have hit the back of the net with the same regularity and Commons admits it has been difficult for the club to replace him.
"In the time I have been here we have found it hard to replace Gary Hooper," Commons admitted.
“If all your forward four – your strikers, wingers and No. 10 – can get 10-15 goals apiece you are heading in the right direction. It means you don’t have to rely on one striker to get 30-40 goals a season."
As Commons says, Celtic have compensated for the loss of Hooper by trying to get more goals from other areas of the team, but they will still be looking for a potent front man this summer.
John Guidetti, Stefan Scepovic and Leigh Griffiths have all competed for the striking role in Celtic's starting line-up this season, but none have scored quite as regularly as Ronny Deila would have been hoping.
Celtic have actually been linked with Hooper in the Daily Record and they reportedly could make a move to try and bring him back to Parkhead.
The striker has struggled for form at Norwich, but he managed 82 goals in 138 games during his first stint at Celtic and it appears his return would be welcomed by Commons.
