Romelu Lukaku called on Manchester United to play with "arrogance and confidence" against Barcelona as they seek to overturn a 1-0 defeat in the first leg of their Champions League quarter-final.

Ole Gunnar Solskjaer's side face an uphill battle at the Camp Nou next week after Luke Shaw's own goal gave Barca a 1-0 win in Wednesday's match at Old Trafford. United rallied after that early setback and unsettled Ernesto Valverde's side, giving Lukaku and his teammates confidence of a memorable turnaround in Spain next Tuesday.
