Ander Herrera says he is still blown away by the special reception he received from Manchester United fans after his first appearance at Old Trafford, back when he didn't even play for the club.
Two years before the Spaniard signed for United in 2014, he made his debut at the famous stadium when Athletic Bilbao visited in the Europa League.
Herrera and his teammates caused a huge upset as they won the match 3-2, though the general feeling at full-time was that they should have won by even more.
