Giggs is one of the worlds best wingers, right now, really? Valencia was by far, I mean by a mile the worst player on the pitch for Utd against Real, and simply hasn't been very good. His highest scoring season.... ever(well in this league) 5, he's got over 5 assists in a full season, once, he got 9. He's never been anything more than average, he's not young, there's little to no potential for him to improve. Taarabt is still improving, he's shown FAR more goal threat and assist potential than Valencia.
He's 22, he got 19 goals and 16 assists last season, Valencia is older(not as old as I thought) and hasn't shown any hint he could be a 10 goal a season winger. yes its hard to compare Taarabt could be crap in the premier league, he was under 20 when he played for Spurs, from how well he played you'd think he'd do pretty well in this league.
Frankly I have no idea where Valencia's reputation comes from, hope? He's done very little of anything at Utd and even less at Wigan. Nani had an excellent season this year but was still less than half as successful as Ronaldo in his best year, Nani can be conceded an excellent winger this season, Valencia's BEST season in 5 years in the league got essentially half the goals and half the assists than Nani did, thats his best season, his average over 5 seasons is frankly, for a top 4 club, pathetic. I also said Taarabt would PROBABLY do better, because he PROBABLY will be better than a not very good Valencia and a 58 year old Giggs. He's 22, has more potential than Valencia by a mile, he might turn out crap, he might be a fantastic winger for the next decade for you, theres potential there, Valencia, he won't ever be brilliant, he's 25, he's shown not even a hint of being a world class winger, not even a really good winger.
