Jack Harrison lifts lid on Leeds United's key pre-match switch after impressive hat-trick at West Ham

The Whites met the Hammers for a second successive week at the London Stadium but turned the tables on their counterparts in the Premier League.

Leeds were beaten soundly in the FA Cup last Sunday but played out a 3-2 thriller in the capital to earn an important three points.

Harrison, who had one top-flight goal to his name ahead of kick-off, bagged an impressive hat-trick to lift depleted Leeds over Europe-chasing West Ham on the day.

Marcelo Bielsa saw Adam Forshaw and Junior Firpo limp off after 20 minutes following the winger’s breaking of the deadlock.

David Moyes’ outfit levelled through a Jarrod Bowen header but Harrison again put the visitors in front from close range at a corner.

Pablo Fornals again restored parity in the second half during a topsy-turvy encounter before United’s wide man showed a killer instinct to lift the ball into the net for a third.

Mateusz Klich saw a fourth strike chalked off thanks to VAR intervention as his effort clipped the narrowly-ruled offside substitute Rodrigo on the line.
