That’s the verdict of former Arsenal star and Sky Sports pundit Charlie Nicholas, who says the Robins can be “awkward” opposition.
United have overcome Burton Albion and Swansea to reach the quarter-finals stage of the Carabao Cup this season.
And Jose Mourinho’s men will be expected to breeze past Lee Johnson’s City with the quality they have among their ranks.
Nicholas has outlined why it won’t necessarily be plain sailing for United at Ashton Gate, despite predicting a 3-2 away win.
“This could be an awkward one for Manchester United,” he told Sky Sports.
“Bristol City are flying at the moment, certainly scoring a lot of goals, and strong enough to have a go at home.
“However, Jose Mourinho has his best player back in Paul Pogba and he’ll also give Zlatan Ibrahimovic a start so they’ll have the physicality and ability to get the job done.
“Jose loves this cup.
“Even with [Manchester] City cantering away at the top of the league he can say ‘we’re in the semis of this, final 16 of the Champions League and second in the league’ and you can’t really argue with that.”
Next up for United in the Premier League is Saturday’s visit to Claude Puel’s Leicester.
