they should buy one who isnt playing in the champions league because players who are currently playing champions league with a team and if they switch teams thats also playing the champions league they cant play in that competition like what happend with balotelli with man city and ac milan that being said barca should buy ter stegen goal keeper from borussia m'gladbach and their defender should be daniel agger from liver pool.
David Luiz.
