they came from behind late on to secure a 1-1 draw at Fulham.

Earlier, Tottenham extended their unbeaten run to 11 Premier League games but were made to work hard for a 1-1 draw at Crystal Palace.
Harry Kane's 15th goal of the season put Spurs in front midway through the
first half but from then on they retreated and allowed Palace to dominate the
