Ryan Giggs has warned Manchester United that Manchester City will win the Premier League title again next season unless there is a marked improvement by the Red Devils.
The Citizens were beaten 3-2 by United on Saturday, but Pep Guardiola's side remain 13 points clear at the top of the table with six league games left.
Barring a cataclysmic collapse, City will lift the title this season, and Giggs believes that they will strengthen further to become more competitive on all fronts.
Speaking about his former side, Giggs told Star Sports: "They have to [improve]. They have to next year, they have to do that.
"Otherwise, City will win the league again, because of the quality that they've got, the transfer window, they're going to improve, they're going to get better players.
"Every season, whoever wins the Premier League, the teams beneath them have to improve. So Manchester United have to next year."
United, currently second in the league, remain in the hunt for the FA Cup this season.
