Spurs went into Saturday’s London derby on the back of successive defeats in the past week to Arsenal and Paris Saint-Germain, conceding nine goals in the process.
Tottenham found themselves behind after just four minutes against their London rivals when Kenny Tete’s effort deflected in off Destiny Udogie at the near post.
Things went from bad to worse for Tottenham two minutes later when Guglielmo Vicario rushed off his line and made a complete mess of a clearance which resulted in Harry Wilson, spectacularly, doubling Fulham’s lead.
However, there was to be no late drama in north London on the pitch - instead it was saved for after the full-time whistle.
Sky Sports’ cameras picked up the right-back screaming ‘Lucas’ several times as the 19-year-old started to walk around the pitch and show his appreciation to the home supporters that had stayed behind.
Porro then stormed down the tunnel, presumably frustrated that he and his team-mates could not find an equaliser to prevent a third straight defeat across two competitions.
Thomas Frank was asked about the incident afterwards and told Sky Sports: "I didn't see the incident so I don't know exactly.
“We are in a tough spell right now and for my players it is about being as calm as possible and doing everything we can to work through it."
