Are Liverpool genuine title contenders or mere pretenders?
With a little help from Manchester City , they will soon find out.
Liverpool go into Christmas top of the league table for the first time since the 2008/09 season, one in which they eventually finished runners-up.
Such is the competitiveness of this season's Premier League, that only two points separate them from fifth-placed Everton.
Getting there is often the easier part. Staying there will take a lot more out of them.
The Etihad Stadium assignment tomorrow morning (Singapore time) will be their toughest of this campaign.
It will therefore be the litmus test of their title credentials.
The Reds have the momentum, helped by an in-form Luis Suarez who has scored 10 goals in his last four outings.
But Man City, a point behind Liverpool in the standings, go into this game as firm favourites.
At home, they have won eight out of eight league fixtures, in which they have scored 35 goals and conceded just five.
Even Liverpool manager Brendan Rodgers admitted that the Citizens look most likely to clinch the league crown.
But this is not the time to preach caution.
