It's hard to temper your expectations without people automatically accusing you of being negative, but Foden is the perfect example.
He's already a 10 goal a season PL Midfielder, won the CL, and scored a hat trick in a Manchester Derby.
Gerrard and Scholes might have done it for longer periods, but more recently, I can't think of many Academy Players at any PL club who've come anywhere remotely close to what Foden has achieved.
He's virtually the 2nd best player in 3-4 positions, but I'm not convinced that he'll ever become that first name on the teamsheet who opponents fear the most. His tends to enjoy moments of brilliance, but just like the CL Final, he never uses it as a springboard for total domination.
Instead I think he'll continue to score 10 PL goal a season which makes him indispensable.
