Manchester City suffered a resounding defeat at the hands of Manchester United in the 198th Manchester derby, losing further ground to Arsenal in the Premier League title race. If Arsenal triumph over Nottingham Forest on Saturday, they could extend their lead to nine points following City's 2-0 loss.

Antoine Semenyo retained his spot in the starting line-up after scoring in his first two starts for the club, but failed to maintain his scoring run in a team that started off weakly and deteriorated. United had already seen two goals disallowed and Pep Guardiola had made two half-time substitutions when Bryan Mbuemo broke the deadlock in the 65th minute. City's reaction was inadequate, and Patrick Dorgu doubled the lead. Here are the player ratings from Express Sport...

Donnarumma: City owe him a debt of gratitude for only losing 2-0 given the saves he made throughout the match. 8.

Lewis: He attempted to tie everything together but it didn't pan out and he was caught napping for the second goal. 5.

Khusanov: By far City's best defender, reading the game well, utilising his physicality and making crucial tackles. 7.

Alleyne: Some shaky passes that failed to find a teammate as he struggled to regain the confidence from his recent games. Subbed at half-time. 5.

Ake: Managed to prevent United from beating him while staying onside, and then slotted in to partner Khusanov. 6.

Rodri: Almost handed United an early lead with a baffling pass near his own box, and his performance deteriorated as the match progressed. 4.

Silva: Despite his efforts, it wasn't enough in a match where City needed to retain possession to create the necessary opportunities. 5.

Foden: Struggled to gel with Doku and Haaland, but it was still surprising that he was substituted after just 45 minutes. 5.

Semenyo: Failed to maintain his scoring run, but there were glimpses of his potential. 6.

Doku: Earned Dalot a booking within minutes for a harsh tackle, but his influence quickly waned and never recovered. 5.

Haaland: Barely had a touch of the ball and when he did, Martinez usually managed to contain him. 5.

Substitutes

Cherki (for Foden, 46): He made an effort and showed willingness, but it was his poor set-piece that led to the opening goal. 5.

O'Reilly (for Alleyne, 46): United exploited his lack of awareness of the last man and he was easily beaten by Cunha for the second goal. 5.

Mukasa (for Haaland, 80): No time.

Reijnders (for Silva, 80): No time.

Ait-Nouri (for Doku, 80): No time.

Not used: Trafford, Bettinelli, Mfuni, McAidoo.
