Leicester City boss Brendan Rodgers admits they weren't at their best for victory over Watford.
Jonny Evans won a penalty and Jamie Vardy converted from the spot, before England international James Maddison made it 2-0 with a clinical strike in injury time.
Despite playing a second Premier League match in the space of four days, Rodgers felt City's fitness levels shone through from start to finish at a foggy King Power Stadium on Wednesday night.
“We'll play better, it's one of those games that can be a stuffy game, but I'm absolutely delighted with the stamina and again, the mentality of the players to keep going," said Rodgers.
“We scored another late goal to close out the game, so that shows you the fitness level of the players and the concentration. Jamie [Vardy] gets another goal and like I said, should have had another penalty.
“We created other chances. Ayo (Ayoze Pérez) had a chance early on, in the first five minutes. However, we can't fault the players tonight. To win seven games on the spin and get another clean sheet, that was terrific."
