There is no denying that Liverpool have great Premier League momentum.
Unencumbered by the energy-sapping toils that campaigning in European competition can bring, Liverpool have amassed a maximum 21 points from their last seven matches, leading the domestic form table and climbing to a healthy second place in the division, just one point behind pace-setting Chelsea.
In combat sports parlance, Liverpool passed a gut-check last night, Wednesday, after gaining a 2-0 advantage but almost allowing Sunderland to leave Anfield with some sort of result, dropping a 76th minute goal to Ki Sung-Yueng.
Demonstrating courage and ensuring they returned to the dressing-room with the victory will stand the club as a whole in good stead as they see out a potentially problematic final seven games including fixtures against Tottenham Hotspur, Manchester City and Chelsea.
"It was nervy at the end but I think that will hold them in good stead between now and the end of the season," said a former Liverpool great, Jamie Carragher, to Sky Sports.
Such mental fortitude can only benefit Brendan Rodgers' team.
Carragher has more: "So often I've been at games where they've been two or three up at half-time and the game is finished. But Chelsea, City and maybe even Spurs will be stronger opposition - top teams coming to Anfield - it will be tight, it will be nervy - so to go through that and come out with the three points will do them wonders between now and the end of the season.
