The Mexican international tallied one of the 10 goals scored at The Hawthorns to cap his season with his 18th goal in all competitions.
Chicharito scored the last Manchester United goal of Sir Alex Ferguson's tenure as manager, with his 63rd-minute strike capping the Red Devils' attacking in a wild 5-5 draw with West Brom.
The Mexican forward, who assisted on Shinji Kagawa's sixth-minute opener, was the beneficiary of a cross from Ryan Giggs, which he redirected from close range and past Ben Foster to give Man Utd a 5-2 lead at the time. West Brom battled back with three goals in quick succession -- including two by Romelu Lukaku to finish off his hat trick -- to force the high-scoring draw.
For Chicharito, he ends the season with 10 league goals and 18 in all competitions. He also managed to score in Ferguson's last match at Old Trafford, tallying the first Utd goal in the 2-1 victory over Swansea City on May 12.
