Would have been a nice signing, but it's not anywhere near as bad as people are making out. He's suited on the wing and having him would have maybe pushed Memphis inside where he is worse off.
What we need is not a winger, it's a player who can play no10/Striker and switch/link with Rooney. Rooney is struggling a bit early on and having someone who would push forward when he drops back would give us that man further forward. The Muller type signing would be perfect, not that we'd get him.
Pedro could have been a player who could maybe have done that but he's not the be all and end all. There are better players for the role than hum, whether any are available are a different matter. Trust in LVG, i'm confident he'll have something lined up.
