After a recent uplift in their results, the pain returned for Manchester City and Manchester United in the Premier League.
City conceded a goal inside two minutes and was overwhelmed in the second half in a 5-1 loss at Arsenal, which trimmed the gap to leader Liverpool to six points on Sunday.
United lost again at home, 2-0 to Crystal Palace, and now has seven defeats in 13 league games at Old Trafford this season — something not seen since the 1890s.
The chances of City winning a fifth straight Premier League title are surely over — the champions are 15 points behind Liverpool with 14 matches remaining — and they must have felt humiliated by the end of the game at Emirates that again demonstrated the new-found hostility between Arsenal and City.
City arrived having won six of its last eight games in all competitions but all is still not right with Pep Guardiola’s team, which let in a sloppy opener when Manuel Akanji was dispossessed near his own area and Martin Odegaard scored.
