The Spanish midfielder hasn’t featured since being substituted at half-time against West Brom and missed the Chelsea, Manchester City and Crystal Palace game.
Having overcome his fractured rib injury, Herrera being ready to play again is a great boost for United going into the Arsenal game.
“Ander’s had terrible luck with injuries,” Mata explained. “But he’s fit now, he’s ready. He’s a great friend, a ‘crack’.”
Despite Fellaini’s improved performances, Herrera’s influence in the middle of the park has been sorely missed and United need him back in the side.
Herrera was extremely important in United’s great attacking football earlier this season and Van Gaal will be glad to have him back.
