Manchester City were unable to break down a stubborn Manchester United defence in a 0-0 draw on Saturday afternoon, with Riyad Mahrez in particular, producing a disappointing display against the Red Devils.

The Algerian winger wasted a huge opportunity to give the Citizens the lead in the first-half, in a game of few chances at Old Trafford.

The 28-year-old was disappointing throughout the game on Saturday and was substituted in the second-half by Pep Guardiola, as the away side chased a winner.

As per SofaScore, the former Leicester City man picked up a 6.8 rating for his display, with only Joao Cancelo, Raheem Sterling and Gabriel Jesus rated lower of the City players who started the game.

During the game, Mahrez had just 23 touches of the ball, which was less than goalkeeper Ederson, who had 36.

The winger could only complete 13/18 passes during his time on the pitch, as he struggled to have much impact against Ole Gunnar Solskjaer's side, in a game that was low on quality.

Mahrez failed with his one dribble attempt during the game, which is an area he normally excels in, so it was clear that he wasn't at his best during the game at Old Trafford.

Whilst he won two out of four of his duels during the game, and lost possession just eight times, he struggled to get involved, as City failed to ever really get in behind United's defence.

Earlier this year, Guardiola was full of praise for the 28-year-old, saying:

“Riyad is an exceptional player. I know how important he is for us.”

“For the quality, the passes and especially his mentality and he is aggressive to score goals."

However, it was clear that Mahrez couldn't really have any impact on the game during the Manchester derby, so it was no surprise that Ferran Torres replaced the Algerian with just under half an hour remaining.

Mahrez will have to improve if he wants to keep his place in this City starting eleven, with Guardiola's side set to face West Brom in their next Premier League fixture on Tuesday.
