- Leicester City sealed a 3-1 success at Brentford in the Emirates FA Cup Fourth Round on Sunday
- Cengiz Ünder, Youri Tielemans and James Maddison found the net, after Mads Bech Sørensen's opener
- Manager Brendan Rodgers pointed to the perseverance of City's performance in west London
- The Northern Irishman also credited his players for remaining calm after falling a goal behind
The Foxes went in at the break a goal down following Mads Bech Sørensen's opener for the Bees, but the visitors regained control of the contest after the interval at Brentford Community Stadium.
Cengiz Ünder's curled finish came just 49 seconds after the restart, before a Youri Tielemans spot-kick and James Maddison's close-range finish set up a fifth-round home tie with Brighton & Hove Albion.
Speaking after watching Leicester's fifth consecutive victory in all competitions - and their eighth game unbeaten - Rodgers pointed to the determination on show from the visitors in west London.
Asked to isolate the key to City's success, the 47-year-old told LCFC TV: "It was just perseverance. We started well in the game and then after nine minutes, we gave away a sloppy goal from a set piece.
"But apart from that that, I thought the performance level was really good. Of course, it was really good in the second half.
"The speed of game [was better], we played higher up the pitch, pressed the game better, and some of the football was outstanding."
Rodgers also revealed that there was no overreaction at half-time to being behind in the game and praised his players for maintaining their performance levels - adding goals at vital moments.
"I thought we had a number of opportunities in the first half, I was really pleased," the Northern Irishman continued. "I reinforced that with players at half-time.
"There was no need to be negative at half-time because some of the football was good. We just had to pay attention to their set pieces.
"They're clever, they're bright, and we gave away a sloppy one, which put us behind in the game, but the reaction from the players was outstanding.
"[In the] second half, the goals, the rhythm of the game, was at a really high level and we played really well."
