Reportedly available for just £6m: Celtic must join four PL sides in race for Benfica wing wizard – view
Roberts needs replacing
Last season, Patrick Roberts was arguably Celtic’s biggest creative influence in the final third as he amasses a huge 19 assists during his 41 league and cup encounters.
As well as scoring 11 goals, the Manchester City attacker has returned to his parent club and the Hoops are in desperate need of replacing the England youth international.
Jonny Hayes is a good signing, but being 10 years older than Roberts, signing a player with that yard of pace still intact is key and Carillo should be that man at such a bargain price.
