Manchester United defender Patrice Evra fears rivals City could go on to dominant the Premier League trophy if they prize the title from their grasp this season.
Evra feels City must be stopped in their tracks fearing one title success would pave the way for future dominance on the domestic front.
"Beware. If City start winning it will be hard to stop them," Evra said as United pursue their bid for a record 20th Premier League title.
"We have to stop them before they start, because they can go far. That's how a big team starts, the first trophy they win.
"They won the FA Cup last year and if they win the league they'll get too much confidence
