Arsenal hero Martin Keown felt Jose Mourinho fluffed his team selection for Manchester United's defeat to Manchester City.

Keown wrote in the Daily Mail: "United had a perfect record in the Premier League this season coming into this game, and I don't understand why Mourinho changed his winning formula.

"The Portuguese had started Juan Mata and Anthony Martial out wide in all three league games prior to the Manchester Derby, but decided to drop them for Mkhitaryan and Lingard.

"Neither played particularly well and Mkhitaryan in particular struggled as Kolarov put him under pressure when in possession. It's as if Guardiola knew the Armenian would be uncomfortable in his first start for the club and asked his full back to take advantage of this."
