Celtic could do with a striker in the January transfer window.
Leigh Griffiths made a return from injury on Saturday to score for Celtic in the Hoops' 3-0 win over Hamilton, but there are no signs that he has finally put his injury demons behind him.
Griffiths, 28, missed six weeks of action between early October and late November and spent much of last season on the treatment table. Though he is a crucial part of Celtic's side, back-up is needed.
Indeed, Celtic only have Odsonne Edouard as their other option up front and he is no stranger to the physio room either. It is more than likely that both players could be sidelined through injury at some point this season.
The Hoops decided to sell Moussa Dembele to Lyon in the dying moments of the summer transfer window, giving Brendan Rodgers no chance of bringing in a replacement.
But the former Swansea and Liverpool manager still has the Dembele money to spend, and he should be prioritising the signing of a striker in the January transfer window.
His attention should turn to Portugal international Nelson Oliveira, who is currently frozen out at English Championship leaders Norwich City. Turkish outlet Fotospor claim Besiktas are interested in signing the 27-year-old star.
Oliveira has failed to even make the bench for Norwich this season, and the Turkish report claims the former Benfica star is available for a bargain £3million.
For such a bargain price, Celtic would be landing a player with 17 Portugal caps - one that has scored in the top tiers of French, Portuguese, Spain and England. He would be an excellent signing for such a bargain price.
