If we sign him, i'd be delighted, cause he is a fantastically talented player, and would be one capable of providing the magic that I believe we are kinda missing having lost Ronaldo.
Robben would improve our team.
However, there are two issues I would have with him signing.
1. Nani. I think he should be given one last season to prove himself - and he needs to be given a decent run in the team to do that. If we signed Robben, his chances of starting often would be diminished. Nani has impressed me in pre-season, and in the games he has played competitively this season. He hasn't been amazing, but he has been very good, and showing great promise and better decision making on the ball.
2. I really do think we should be looking at the central midfield area before looking to the wing again.
So, I would be delighted if we signed him, cause he is a very talented player, but I wouldn't be too upset if we decided to give Nani a proper go. Also, Ljajic should be coming in January, and he is another promising and skillfull player.
