Manchester City youth coach Alex Gibson rates FA Youth Cup finalists Arsenal as one the best teams in recent years.
He told City's website: "That is one of the best sides we have ever faced in my 11 years at the club. They were one of the strongest sides, both from the technical point of view and physically.
"They had a height advantage in many areas - set plays were always going to be a problem, but we have some very tidy players that will go on to do very well."
