Yaya Toure has warned Manchester City to be wary of a "very angry" Jose Mourinho in next season's Premier League title race.
Pep Guardiola's side finished 19 points clear of second-placed United as they romped to a record-breaking title triumph in 2017-18.
City became the first team to score 100 points in England's top flight, while they also recorded the most wins (32), the most goals (106) and the biggest goal difference (79) in a remarkable campaign.
With United having been left in their neighbours' wake, Toure, who left the club at the end of the season, expects a backlash from Mourinho in 2018-19.
