Manchester United have been warned not to make a 'huge mistake' and 'underestimate' Atalanta by Amad Diallo, ahead of the youngster's current club facing his old side in the Champions League.
United are in desperate need of a positive result in their next crunch clash tomorrow after their struggles in the Premier League and Europe - with Ole Gunnar Solskjaer under pressure due to his team's torrid start to the season.
It is unlikely that Amad will feature against Atalanta at Old Trafford as United bid to leapfrog their opponents at the top of Group F, but the tricky winger has insisted that Gian Piero Gasperini and his men will pose a stern test.
