Chelsea rallies for a wild win at Tottenham
Palmer scores the winning goal from the penalty spot as victory moves the Blues to third in the rankings
Marc Cucurella was left red-faced after his choice of footwear proved his undoing, twice falling over and being punished as Tottenham took advantage to surge ahead 2-0.
It was all smiles between the Spaniard and Maresca at the end, however.
"He said to me after the game that he was trying to bring emotion to the game!" Maresca told Sky Sports.
"No, being serious, to come to this stadium against this team and be 2-0 down, but continue then with the same plan on and off the ball and then second half we changed things tactically. I think overall we deserved to win.
"It's more a question for Marc. They are mature enough to decide what boots they need for the game. The most important thing is that we were 2-0 but we continued the same way to create chances."
Arsenal, meanwhile, is getting most of its goals from set pieces.
William Saliba — one of two scorers from corners in the 2-0 win over Manchester United on Wednesday — repeated the trick in the 52nd minute against Fulham to earn his team a point at Craven Cottage. Raul Jimenez put Fulham ahead in the 11th.
Arsenal trimmed the gap to Liverpool to six points but this will go down as a wasted opportunity.
Bukayo Saka had what looked like being a winning goal for Arsenal ruled out for offside against fellow winger Gabriel Martinelli in the buildup in the 88th.
