Wayne Rooney came under increased scrutiny after Birmingham slumped to their ninth defeat in 15 games since he took charge, as Leeds bounced back after successive away losses.
First-half goals from Patrick Bamford and Dan James laid the platform for a comfortable victory for Daniel Farke’s men, a welcome antidote to post-Christmas defeats at Preston and West Brom.
Crysencio Summerville added a third in the second half as the home crowd taunted Rooney with chants of ‘you’re getting sacked in the morning’.
Birmingham supporters were heard joining in with the chants, with the away fans also heard singing 'Wayne Rooney, get out of our club'.
