With Liverpool having seen Manchester City draw 2-2 with Newcastle moments before they kicked off at Anfield, it took 18 minutes for them to take a deserved lead after Gross fouled Alex Oxlade-Chamberlain outside the Brighton area.
Brighton had shown a certain threat and when Alison rushed out of his goal in the 76th minute, he had no choice but to fire him, a rush of blood that would drive him out of the Merseyside derby.
Brighton boss Graham Potter was pleased with the performance of his side but felt they paid the price for some lapses. There was no offside and then it is a tricky situation.
"I felt that the boys were a little exhausted after playing a high intensity match, but we had the chance to score the fourth goal, but then in the Premier League, the match is still alive", said Mourinho.
"With his cold feet, he couldn't shoot the ball as far as he wanted".
"Even the goal-kicks are hard with cold feet!"
Adrian was caught out by a quick free-kick from Dunk, with Klopp of the opinion that a new man on the field should have been given more time by the match official to get his bearings.
"It was very clever from Brighton but the keeper has just come on and is trying to set the wall". They are trying to get used to each other and the referee lets it go like this.
"I think we are playing the way that is necessary to win", Alisson continued.
- Liverpool are unbeaten in each of their last 98 Premier League games at Anfield when leading at half-time (W89 D9), since a 2-1 defeat to Arsenal in December 2009. But the club have enjoyed a dream weekend where they have now extended that lead to 11 points and surely no team is catching them up now?
- Liverpool have registered 14 consecutive home wins in the Premier League, their second longest home top-flight winning run behind a 21-game streak between January-December 1972. Leicester, meanwhile, play Everton on Sunday where they will be hoping to reduce the gap behind the leaders to a still significant eight points. He starred in the 3-2 win at West Ham in Mourinho's first game in charge, scored the goal that started Spurs' recovery from 2-0 down in the 4-2 win over Olympiakos in the Champions League, and on Saturday scored twice in a 3-2 win over Bournemouth.
"Result-wise, it is an incredible period for sure, but we don't want to think about the last 14 games - we actually are concerned about the next one, which is on Wednesday against Everton and is a big one".
