He was far too young when he left Athletico to be anywhere near the first team, and he was also behind De Gea, as for better then Howard, this season he has been better the most of the keepers in the Premier League, not just Howard, of course he is better then Howard but he did stay a few seasons to long.
That aside the talk of Heaton is laughable, how many seasons has he played of top flight football at his age? We're talking about trying to compete for top 4 spot and some think we can do that buying a keeper from the team in 12th place? lol
