It's been a dreadful first half for QPR after they found themselves 3-0 down after 32 minutes to Brentford. An Ariel Borysiuk own goal handed the Bees the lead before John Egan added a second and Neal Maupay a third. However, Darnell Furlong pulled one back for the R's on the stroke of half-time leaving QPR with it all to do in the second half.

15' Furlong gives away the ball and Neal Maupay picks it up before pulling wide of Ingram's post from 18-yards. Sloppy from Rangers.
