Pablo Zabaleta has admitted that Anthony Martial has been "very impressive" since joining Manchester United from AS Monaco during this summer's transfer window.

The striker's £36m transfer fee drew criticism from some, but the 19-year-old has scored five goals in his first nine appearances for Louis van Gaal's side.

Ahead of this afternoon's Manchester derby, the Manchester City defender told the Daily Star: "United have enough quality, especially this lad who has had a very impressive start to the season and is going really well.

"He's a powerful, skilful player who has scored a few goals, a big one in Moscow. Martial is a really good quality player. He is young and I know they paid big money for him but he is doing really well."

Martial was on the scoresheet in midweek, netting the equaliser in the 1-1 draw with CSKA Moscow in the Champions League.
