It's not just one season though, if we sign a CB then the chance of them signing a 3 year contract or less is very small.Our 4 CB's last season played
55 games (Laporte)
39 games (Stones)
33 games (Otamendi)
26 games (Kompany)
If you seriously think a 19 year old with no experience is going to turn his nose up at starting a minimum of 26 games, you're living on another planet. Not taking into account Fernandinho's 35 and covers other positions so if Garcia is a prodigy he could easily end up as 3rd choice.
And where else is a teenage CB with no experience going play that much? In the Champions League and going after trophies? No where.
