He has played against top oppositions this season. Arsenal for example. He did well against those as well so I can't understand what you mean. I read somewhere that Bamford and José said that to be "emotionally ready" for the PL (I know that's José logic but he is in charge so it does matter) you must be at least 21/22 years old. Bamford is reaching that age, lets just see if he is also talented enough.
