Premier League high-flyers Leicester City had to come from behind to avoid an FA Cup upset at Championship promotion hopefuls Brentford.
The hosts took an early lead when Mads Bech Sorensen poked in and had the better chances during a first half when a much-changed Leicester side struggled for fluency.
But the Foxes were transformed after the break, equalising 49 seconds after the restart as James Maddison fed Cengiz Under for a sweeping finish.
Five minutes later, Youri Tielemans was tripped in the box and converted the resulting penalty, while Maddison deservedly got on the scoresheet by following in a rebound.
