A win against Swansea meant that Mauricio Pochettino’s team reached 55 points, surpassing their previous highest Premier League points tally of 54 set after a 42-game season in 1994-95.
The feat comes as further confirmation of considerable strides made under Pochettino and glittering young talent like Luke Shaw, Adam Lallana and Jay Rodriguez.
“The three points were massive,” said Pochettino, after England striker Rickie Lambert’s scrambled injury- time goal sunk Swansea.
Lambert capitalised on an unexpected late opportunity after Swansea skipper Ashley Williams’ attempted clearance ballooned high and behind keeper Michel Vorm, dipping into the net off Lambert’s back.
