The summer arrival from Barcelona scored in Chelsea's Europa Conference League win at Astana last night.
Speaking on TNT Sports, Cole said: "Marc Guiu! He must have watched Luis Suarez as a young man in Barcelona. He's got great movement.
When dissecting Guiu's first goal, he said: 'He makes an inside to outside run and this is all about ability and athleticism as he just drives past these centre-half. That is exquisite from a young man. It's a great finish."
At fulltime, Cole also said: "I love Marc Guiu. Like I said, this is exactly the game where he'll give you energy and aggression with his running.
"Just think, this kid is 18, how big and strong he'll be when he's older. I think Chelsea have got a real gem there.
"I think he's a Chelsea player but maybe it's a year down the line. We don't know the path he's going to choose but he's certainly very talented."
