While the result was a missed opportunity, all attention is now firmly focused on a Porto side who, like Liverpool, remain undefeated in their opening eight games of the campaign.
It presents another challenge for the Reds in what is their sixth game in just 16 days, with training on Monday coming just 41 hours after the final whistle at Brentford.
For the 12 players who feature over the weekend, it was just their second day of recovery and changes could, therefore, be in store in the second Champions League game this season.
The No. 8 has obviously seen the pain settle after striking the ground at Carrow Road, leaving the manager with a number of options including Jordan Henderson, Fabinho, James Milner and Curtis Jones for Tuesday’s game.
As per normal, the Reds started training with a light warm-up and ball work as Klopp and his backroom staff watched on.
Mohamed Salah, meanwhile, continues to push his way toward claiming the title of Liverpool’s most prolific goalscorer in the competition as he is currently just three of Steven Gerrard’s tally of 30.
There were no youngsters present on this occasion with a big week ahead for the academy as an under-19 squad will also meet Porto in the UEFA Youth League on Tuesday.
