Robin van Persie completed his hat-trick with a fantastic free-kick.
After a barnstorming run by Wayne Rooney, Danny Welbeck was fouled on the edge of the box and there was only ever one person who was going to take the free-kick – Van Persie.
He stepped up and, after a Rooney dummy, left the Olympiacos goalkeeper flat footed to make it 3-0 and put United ahead in the tie. Bedlam.
Of course, Olympiacos still only need one goal to go through on aggregate so United cannot afford to sit back and rest on their laurels yet.
Attack attack attack.
