Maddison ended 2020 in top form, linked with a move to Arsenal as well as a spot in Gareth Southgate's Euro 2020 squad, but things haven't gone swimmingly since, until today.
Leicester took an early 14th minute lead when a cleared corner fell to Youri Tielemans who did what he does best, blasting in another sensational long-range effort.
Brentford were reeling from an earlier offside call denying Ivan Toney the opener, but the Bees continued to outwork the Foxes, finally getting their reward in the second half.
Mathias Jorgensen put Brentford level with yet another set piece goal when he flicked in Mathias Jensen's corner over Kasper Schmeichel and into the far corner of the net.
The goal turned out to be the exactly the wake up call Brendan Rodgers' side needed, with Kelechi Iheanacho brilliantly linking up with Patson Daka to put the summer signing clear of the offside trap, where he then unselfishly squared to Maddison for an easy tap-in.
Leicester leapfrog Brentford into the top four competition, winning three matches in a row for the first time this season.
