Sutton said: “Roberts might be a sensational signing. I hope he is. But he has arrived as a -year-old with limited first-team experience and it’s a big gamble putting Champions League eggs in his basket at this stage.”
Roberts agreed an 18-month loan deal with Celtic, joining to experience consistent first-team football rather than sitting on the bench at Manchester City.
He made his debut for the Bhoys last weekend, coming on as a second half substitute, and it is expected that the teenage winger will start featuring more and more as the season wears on.
The benefit of signing the 19-year-old on an 18-month loan means that he can spend all of pre-season with the Bhoys, and aid them with their attempts to get into the Champions League next term.
He will establish himself in the first-team before the end of this campaign, and start next season as a key part of Ronny Deila’s team.
However, Sutton does not want Deila to put all his faith in the youngster, as he is still only a teenager, and qualifying for the Champions League is a tough task.
That pressure on Roberts could actually do more harm than good, and it could stunt his development if the youngster is shouldering the weight of an entire club next term.
