The long-term future of the United academy graduate, who spent last season on loan at Lazio, is unclear but nobody will forget his strike against Thomas Frank's men.

It was a match of great goals, started by promising 19-year-old Anthony Elanga producing an excellent volleyed finish from an Aaron Wan-Bissaka cross in the 12th minute.

Brentford produced a moment of magic of their own eight minutes later when Shandon Baptiste hit a swerving volleyed effort from the edge of the box that went in off the woodwork.

Pereira's stunning goal early in the second half was the pick of the bunch but it did not prove the winner as substitute Bryan Mbeumo curled home smartly after half-time introduction Diogo Dalot failed to intercept a ball down the line.
