Manchester City remain favourites to win the Premier League ahead of Liverpool, according to former Red Jamie Carragher.
Liverpool have made a perfect start to the league campaign, winning their opening four matches to hold a two-point lead over their title rivals City at the top of the table early in the season.
Jurgen Klopp's men pushed City all the way last season, achieving a club record 97 points and only losing one match for the campaign, before Pep Guardiola's side snuck home by a point to defend their title.
Carragher, who won the Champions League during a stellar career at Liverpool, believes City are still favourites despite the Reds' fast beginning to the season.
"I think it's a bit early yet. I think we've got to probably wait until Christmas," Carragher said on Wednesday.
"I do feel around about Christmas time Liverpool and City will have a substantial gap and it looks like there's a little bit of a gap at this moment.
"But I still think City are favourites and are the best team in the Premier League at this moment because they won the Premier League and they proved that last season.
"So, I think it's still on Liverpool to overtake City but they're more than capable."
The Reds started the season with a thumping 4-1 victory over Norwich prior to winning the UEFA Super Cup on penalties against Chelsea.
After a hard-fought 2-1 victory at Southampton, the Reds comprehensively defeated fellow top-six team Arsenal at Anfield in a comprehensive 3-1 win.
Their last result was an impressive 3-0 result at Burnley which sent the club into the international break in a positive fashion.
Manchester City, who beat Liverpool on penalties in pre-season's Community Shield, dropped two points in a 2-2 draw against Tottenham at the Etihad in their second Premier League fixture.
Their other league matches have been comprehensive wins over West Ham (5-0), Bournemouth (3-1) and Brighton (4-0).
Liverpool (12 points) will have the chance to extend their lead over City (10 points) when they host Newcastle United in the lunch-time kickoff on Saturday.
City will have the chance to respond later in the day as they travel to promoted high-flyers Norwich City.
