Manchester United technical chief Darren Fletcher saw West Brom's 1-1 draw with Watford on Monday night.
Fletcher was at the Hawthorns on Monday night and saw Watford's Ismaila Sarr score a wonder goal.
The Senegal winger made headlines as he broke the deadlock from inside his own half, just ten minutes into the Championship game - after catching West Brom's David Button off his line.
Fletcher was posted to the game to continue United's assessment of the Watford winger, says the Daily Mail.
Sarr's agent has made it no secret that he is reluctant to endure a season in the Championship.
