- Facundo Pellistri (90'+3')
- Nico Williams (29')
- Aitor Paredes (66')
Nico Williams opened the scoring for visiting Athletic in the 29th minute and looked headed for a win as they prepare to begin league play in Spain in less than a week.
However, the visitors were left to play a large portion of the second half down a man after Aitor Paredes was sent off in the 66th minute for a bad foul on Hannibal Mejbri.
With time running out on Erik ten Hag's rotated side, Harry Maguire headed a long ball from the left side of the penalty area back across and Pellistri pounced to level the score before the referee's final whistle.
