Mate, every top team has better players than those I mentioned in their positions. Look at Barca, Real, Bayern or even Atletico, they are miles better.Madrid aren't the only team who can win the Champions League. And it's chicken and egg - players reputations are made by winning trophies... before they win them they aren't seen as players of that calibre. Unless you're going to totally buy in a team of XI Galacticos, then you need players to rise to themselves to that level and make themselves legends. So that's what I look for more - whether a player might have that in them, and Smalling I believe is capable.
I think that with this signing we are very good and could win the league, but talks about winning UCL are very premature. Our defense at the moment is absolutely atrocious to even suggest that. If Smalling improves, Bailey does well, Shaw continues when he left before the injury and we get a right back/Darmian improves, that is something else, but so far we are far from a title winning UCL.
