Leicester to continue this concentration.
Claudio Ranieri is convinced his side have plenty of fight in them after securing a 1-0 win over Watford away at Vicarage Road.
The triumph over the Hornets extended their lead at the top of the Premier League table to five points.
Riyah Mahrez broke the deadlock for the Foxes in the 56th minute with a sublime strike, as his 15th league goal of the campaign sealed yet another win for Leicester - who are closing in on a Champions League spot.
"It was a difficult match but now every match will be difficult, not only for us, but all the teams,” Ranieri told Foxes Player HD. “For us it was important to give this kind of answer to everybody.
“We want to fight. I don’t know what we will do, but we will fight every match. We want to continue with this concentration, with this ability to be strong and so close to each other.
“Today it was a tough match, but we created four or five chances to score a goal. Two in the first half and two in the second, and then we scored a fantastic goal with Riyad [Mahrez]. But all the players made a fantastic performance.
“I want just to see my players fight and play as well as tonight. Now my focus is on Newcastle (on Monday week) because it will be a really tough match.”
The Italian added: “I have very good players who don’t play but deserve to play. King scored a fantastic goal in the last match and today he was on the bench. But when I called him he was already ready. “It was important because in the first half there were more Watford players in the middle than us. We played just with two, with N’Golo and Drinky (Danny Drinkwater) and they suffered a lot because there were so many players there and I wanted to help them. “In the second half it was much better. We kept control and scored a fantastic goal. “It was a wonderful goal. Riyad shot very well but it’s important how he works for the team. The team is the boss. He has quality but he also plays very well when we defend.”
