Manchester United fans were left fearing the worst when Louis van Gaal started Antonio Valencia at right-back for the crucial game against Manchester City.
The Ecuador international has struggled in Manchester United's recent games, and, charged with the task of stopping Raheem Sterling, he seemed like an obvious weak point in the Red Devils squad.
Indeed, it was already being theorised that Valencia would once again find himself being substituted by Van Gaal as early as half-time.

But Valencia has finally come good, putting in a stellar first-half performance at Old Trafford. So much so that he started trending on Twitter as a result.
Not only has he kept Sterling quiet, but he has also caused Man City's left-back Aleksandar Kolarov all sorts of problems. Squawka have also claimed that Valencia completed 14 out of 14 passes in the first 25 minutes.
