Completely false. McLean is a championship player, while Valencia was named Manchester United player of the year only two seasons back.
You lot really are a fickle bunch. No need to go overboard on this - he's still one of the best wingers in the country and in his day is absolutely unplayable. He had a poor season last year but I actually think the signs this term are quite promising. Rather than the tentative winger we saw last season, he's started taking people on again, running into space and smashing it into the box rather than dilly dallying and passing it back. His one footedness has been done to death and it seems a real weakness when he's off colour but the type of player he is - rarely cutting inside and rather looking to beat his man and cross all the time, it doesn't seem to matter at all when he's fit and firing. He's clearly a confidence player and that was something he lacked last year, but I think by the end of the season you'll all be singing his praises again. He's still an absolute tank of a winger and is still a great option for us.
