Owen Hargreaves admits Manchester United 's display will have dealt Barcelona something of a reality check after they were held at the Nou Camp.
The Catalans are comfortably sat top of LaLiga and welcomed the English side to Catalunya, but will need to win at Old Trafford if they are to progress in the Europa League. United continue to develop under Erik ten Hag and put themselves in a position to win when they went 2-1 up.
Barcelona managed to battle back thanks to Raphinha, whose cross evaded everyone to level the contest. Neither side could find a winner but Hargreaves is confident that the Spanish giants will have been taken aback by United's display - and be fearful of what they could produce on their own patch.
