Birmingham City beat Burton Albion in the FA Cup to progress to the 4th round of the FA Cup.

It only took one goal to separate these two teams in a closely fought encounter with Sam Gallagher's goal the difference between the two sides.

Jacques Maghoma set up Gallagher, who notched his fourth goal in five games for the Blues.

Gallagher's form has been a major part of Birmingham's recent revival, which has seen them stay undefeated in 2018.

The forward, on loan from Southampton, is finally starting to show why Harry Redknapp wanted to pay a hefty loan fee to bring him to St Andrew's.

But having been forced to play on the wing for most of his time at Birmingham so far, the 22-year-old is now thriving when deployed in a centre forward role.

Here are how the Birmingham City fans reacted on social media to Sam Gallagher's display.
