The Europa League semi-finalists lit the touch paper on Thursday night after two enthralling games between Manchester United and Roma and Villarreal and Arsenal.
Both games dished up eleven goals combined, with the Red Devils blowing away the Serie A side and looking nailed on to reach the final after a brilliant attacking display in the second half saw them romp to a 6-2 advantage.
There were some top performances at Old Trafford, including from veteran forward Edison Cavani, but also some displays to forget on the opposing side as Chris Smalling and Henrikh Mhkitaryan failed to impress on their return to the club.
