With the German leading his first game as Reds manager, his new side ran hard and pressed high throughout, with the physical toll taken on the likes of Lallana clear.
Question marks were raised over Lallana’s role immediately after Klopp’s arrival in October, but the midfielder has since confounded those.
This was magnified on Saturday, as Lallana covered a remarkable 12.5km, according to Opta.
Though the season is only three games old, this set the record for the most distance covered by a single player in the Premier League in 2016/17.
The England international has battled against concerns over his fitness under Klopp, no longer needing to be substituted around the 70-minute mark as he did under Mauricio Pochettino at Southampton.
This serves to highlight the positive work done by Klopp and his backroom staff, with newly appointed head of fitness and conditioning Andreas Kornmayer no doubt playing a major role.
Liverpool will need Lallana to complement this hard-running style with more of an end product in front of goal, however.
But he did showcase his creative prowess at White Hart Lane, and arguably should have registered an assist, with Sadio Mane‘s second-half strike questionably ruled out for offside.
Lallana can be seen on international duty with England in the coming days, with the midfielder named in Sam Allardyce’s first 23-man squad.
The Three Lions take on Slovakia in a World Cup qualifier on September 4, and Lallana could be central to Allardyce’s plans.
