Manchester United missed a golden opportunity to force their way into a commanding Champions League spot as Southampton's late equaliser resulted in a 2-2 draw.
After being restricted to settle with just one point, Manchester United now have 59 points, behind the fourth-placed Leicester City on goal difference.
Stuart Armstrong scored the opening goal of the match in the 12th minute, putting Southampton ahead of the Ole Gunnar Solskjaer-led side.
However, Marcus Rashford scored an equalizer in the 20th minute and three minutes later, Anthony Martial handed Manchester United a one-goal lead.
Manchester United successfully maintained their lead up until the 90+6th minute when Michael Obafemi's stunning goal ruined hosts' hopes of climbing to the fourth place on the table.
Manchester United will next play against Crystal Palace on July 17.
