Jurgen Klopp admits Liverpool’s title defence is over after their alarming collapse at Leicester.
The Reds are 10 points behind leaders Manchester City having played two games more following Saturday’s 3-1 defeat.
Alisson’s mistake, when he raced out of his goal and collided with Ozan Kabak, allowed Jamie Vardy to put Leicester ahead with nine minutes left.
Alisson turned a Vardy effort onto the post and Barnes then made it 3-1 after latching onto Wilfred Ndidi’s pass to lift the Foxes above Manchester United.
“This was going to be a good measure of the development of the team. Our reaction throughout the game was very good,” said boss Brendan Rodgers.
“It was a fantastic win against the champions, I thought we deserved it.
“They made a good start to the game. In the first half we were a bit more passive than I would have liked.
“If you are going to play against a top team you have to be aggressive with and without the ball. They are a top side, that’s why they are champions.
“Whatever happens the players have shown maturity and consistency. This group has got big potential and just needs time and consistency.
“Just missing out (on the top four) last year has helped and this year we are seeing them cope better.”
