I know that...... but he is still capable of doing things other players could only dream of or simply aren't capable of. It's nice to have someone in your team who can offer that at any moment despite how poorly they are playing.
Atletico Madrid is a bit of a silly example, they had a very good team and a better defence than us at the time so lets just leave it at that. I'd take Griezzmann any day of the week over Pedro, I don't even rate Pedro that much, only wanted him as a squad option as we're lacking for good cover.
Oh and to ThearteofDreams, I never said we needed a team of stars at all, fact of the matter is we don't even have many... Rooney, Mata, Schweinsteiger? That's the only truly 'stars' all the population would class as.
