Steven Gerrard expects Arsenal to retain the Premier League title, but says three other teams will also "pull away" from the chasing pack.
On Sunday, defending champions Arsenal beat Liverpool 1-0 to return to the top of the Premier League table.
Previous leaders Manchester City suffered another unexpected defeat, losing 1-0 at home to Brighton & Hove Albion. Arsenal took advantage by winning at Anfield thanks to a first-half goal from Havertz.
Arsenal's latest performance has convinced Gerrard that the Premier League trophy will stay at the Emirates Stadium, after Mikel Arteta ended the club's 22-year wait for the title last season.
But Gerrard believes three other clubs, Manchester City, Liverpool and Chelsea, will also "pull away" from the rest of the league and are capable of challenging Arsenal for the title.
"You've got to give Arsenal credit, because that's how you win leagues: by going to places like Liverpool, staying strong and united, and producing a different type of performance," Gerrard said on The Overlap Daily.
"That game was full of guts, fight and togetherness, and they eventually came out with the win. They'll understand that at the end of the season, if they win the league, which I think they will (I haven't changed my mind since the start of the season), they'll look back at that game more often than the games where they looked brilliant and won by four or five goals, because I'm sure they'll do that at times."
"They'll look back at that game and think: we went to Anfield, the fans were hostile, Liverpool played tough, Andoni Iraola has made this Liverpool team much better, Liverpool played well, and we still managed to get three points there."
"So that could be huge for Arsenal. At the moment, Liverpool are nine points behind. If Liverpool want to challenge for the title, they still have a lot of work to do."
"But this Arsenal team looks like they can beat opponents in different ways. I think that might be what sets them apart."
Brighton & Hove Albion are third in the Premier League after their away win against Manchester City. Gerrard believes Fabian Hürzeler's team is a strong contender for the top four, but not yet for the title.
"I'm going to stick my neck out and say I think they will fall away from the title race, but that's not a criticism, because I think they are a top team with a top coach," Gerrard added.
"I just think that to go all the way, the stronger teams in the league will pull away slightly. But I certainly think they are strong contenders for the top four and currently the most dangerous opponents in the league, because they play fearlessly."
"Everyone knows their role in the team, both with and without the ball. I think they've made huge improvements defensively. And they have so many dangerous players, players who are comfortable on the ball."
"Their football is fantastic. I think Brighton & Hove Albion are more of a threat to the top-four contenders, because I think they will challenge for a Champions League spot."
"In a long season, you face so many different challenges in the Premier League. I just feel that, in terms of the Arsenal squad, the Manchester City squad and the Liverpool squad, over 38 games these three teams, and Chelsea (when you look at Chelsea's form in the second half of the season), will pull away slightly."
"But I think Brighton will try, they will give their all, and I really want to see how far they can push themselves. In my opinion, they are not title contenders."
