Claudio Ranieri reiterated the importance of maintaining a fighting spirit, following the 3-1 defeat to West Ham at London Stadium.
Goals from Chicarito, Issa Diop and Michail Antonio was enough to give the Hammers the win.
“We started very well,we created some good chances and scored a goal,” said Ranieri.
“We suffered a lot on our left flank and set plays. It was a pity that the referee was covered for the handball by Chicharito.
“I hope for VAR next season could make it better. Now football is so fast and there are so many players in the box.
“For the referee, it’s very difficult to see everything. For this reason, VAR could make it better. It exists in Italy, in the Champions League and VAR will be important in England to help the referee.
“After the draw, West Ham increased their confidence, moved the ball very fast and we were a little scared.
“We started well, we should’ve continued playing. In the second half, it was much better. We had more control of the game, but without creating chances.
“For us, I know it’s tough, but we must believe. We must continue to fight because I don’t like players who give up. I know it’s very difficult, but we must fight.
“Of course, when you score a goal, you increase your confidence. You see the draw come from handball and it creates tension, but I don’t want this, we have to always fight.
“They were very dangerous on set plays - we knew that and they were better than us.
“The level of confidence increases when you win. Now, our last victory was a long time ago. It’s important that we continue to fight. In training, they train very well, which means they believe.
“We will fight together. If you fight, you may have a chance. If you don’t fight, you’ve lost before play.
“I believe in every one of my players. They have very big hearts. They have to believe, and something will change.”
