Followers of Tottenham Hotspur's social media output may have seen the club's contribution to Halloween celebrations this week.
A masked Kyle Walker was filmed (see below right) jumping out and scaring—well, attempting to in the case of a nonplussed Jan Vertonghen—a number of his teammates, as well as assistant manager Steffen Freund.
Halloween hi-jinks may be over and done with, but Tottenham still have some reasons to be fearful as the season heads into November.
Sunday's opponents and top four rivals Everton have won their last two games and have only lost once in the Premier League this season—a 3-1 defeat at Manchester City. At Goodison Park, their unbeaten run includes an impressive 1-0 victory over Chelsea.
Those looking to the recent past may look to scare Spurs by pointing to their recent record on the blue half of Merseyside—a winless run of six games since they beat them 2-1 in February 2007.
As his side prepares to take on the in-form Toffees, perhaps slightly more frightening for Spurs manager Andre Villas-Boas will be the injury concerns that surround a number of his players.
In front of the Frenchman, Villas-Boas revealed in his team news on TottenhamHotspur.com that his defense will yet again be without the services of Danny Rose. Possibly joining him on the sidelines is fellow full-back Kyle Naughton who was described as having "a 50-50 chance of making it."
As a result, Vertonghen will almost certainly continue at full-back alongside the likely pairing of captain Michael Dawson and Vlad Chiriches in central defense. Completing the back four will be Kyle Walker at right-back—probably not wearing a mask.
With Roberto Soldado nailed on to continue up front following two goals in two games, it is the midfield positions that yet again offer most uncertainty as to who will fill them.
Villas-Boas revealed Nacer Chadli is definitely out after suffering a hamstring injury versus Hull, but he can again call upon the services of Etienne Capoue after he was an unused substitute in the same match.
The Frenchman's return adds to the competition for places in central midfield, though he will probably have to bide his time a little longer for a starting return.
Sandro was rested midweek, and would be a sensible choice in shoring his own side up against one of the division's most dynamic midfields.
While being aware of the threat posed by the likes of Ross Barkley, Kevin Mirallas and former Spur Steven Pienaar, Villas-Boas will not want to concede the initiative to them entirely.
Paulinho's greater goal threat may just give him the nod over Mousa Dembele here. As tempting as it may be to also play the Belgian alongside the two Brazilians in a three-man midfield, the fact that Lewis Holtby was on the bench versus Hull suggests he may be restored on Sunday having had his rest.
Having both been given the night off on Wednesday, Aaron Lennon and Andros Townsend should start against Everton. As well as being tasked with running at Leighton Baines and Seamus Coleman, they will also be required to use their pace in helping stop the attacking full-backs turning the tables in the Toffees' favour.
The battle for the flanks will be just two of numerous fascinating contests in a match in which both clubs will looking to establish a late autumn semblance of superiority over the other in the race for a top four place.
