Even after signing Turkish forward Nadir Ciftci from Dundee United earlier this summer, it seems that Celtic boss Ronny Deila is still on the lookout for new striking options.
The Scottish Sun reported earlier today that the Bhoys have lodged a bid to sign former Celtic striker Gary Hooper on a season-long loan deal, with the forward currently out of favour at Norwich City.
Hooper, 27, spent three years with Celtic having joined from Scunthorpe United in 2010, and with 82 goals in 138 games for the Bhoys, Hooper was a real hero during his time in Glasgow.
In 2013, Hooper returned to England with Scunthorpe, but with just 20 goals in 69 games, he hasn't been able to replicate his Celtic success at Carrow Road.
With Stefan Scepovic struggling to make an impact at Celtic, manager Deila may look to sign another forward - and it's believed Hooper is his current top target.
Celtic fans have been reacting to the rumours throughout the day, with most suggesting that they would love to see Hooper back at Celtic Park after such a successful spell previously.
However, others believe that Celtic shouldn't be looking to re-sign a player who left the club two years ago, with some concerns over his suitability for Deila's tactics.
Here is how Celtic fans reacted on Twitter to reports of Hooper's potential return to Celtic Park this summer...
Would be absolutely delighted if we could bring Hooper back !! Think of the partnership he could form with Griffiths or Ciftci #Celtic— olivia mcghie (@oliviarose18xx) August 17, 2015
I for one would have Hooper back at Celtic in a heartbeat #Celtic— Danny Harkin Jnr (@DannyHarkinJnr) August 17, 2015
Absolutely don't want Gary Hooper back. Walked out on Celtic to enhance his England chances now look at him. Reserve player. Do better.— Chris (@ChrisMcCabe) August 17, 2015
Would like to see Gary Hooper back at Celtic but he'd need to adapt to fit into Ronny's system.— Buff Egan (@buff_egan) August 17, 2015
Of the 24 attempts Celtic had at goal at Rugby Park last week, Hooper would have scored a dozen of them. Natural, instinctive finisher.— David McSheffrey (@RadicalCelt) August 17, 2015
Celtic should be spending money on bringing in a quality striker permanently not getting Hooper on loan who left us for the money— liam (@LostInBeats) August 17, 2015
Hooper was a great fit for Celtic, he left and was replaced by Griffiths - wouldn't be fair on Griffiths to bring him back.— StMiley (@StMiley) August 17, 2015
