They were also 24 and came in from different leagues. Alexis hasn't been that good this season even for Arsenal truth be told. We just had it down to him downing tools due to not wanting to be at Arsenal anymore but there might be more to it than that.I have to remind myself that he's only been playing for MUFC for only a few weeks. Both Vidic and Evra came in mid season and took a little while to get going and I'm sure we'll see Sanchez play to his potential next season.
That said, there have been flashes of nice play so I hope him having the summer off for the first time in a while (last summer he was at the Confederations Cup) will do him well.
