Richarlison could miss the chance to play at Goodison Park for the first time since departing Everton last summer, when Tottenham Hotspur travel to Merseyside on Monday in the Premier League.
After joining for £60m last summer, he is still yet to get off the mark in the league after 19 appearances, but he did score here for Watford in his last game as an opposition player at Goodison Park in 2017.
However, after going off early against Southampton, and missing Brazil duty over the international break, Richarlison was absent from training this week, meaning he is a major doubt.
Arnaut Danjuma may also not get on the pitch, but he will be castigated by the Goodison faithful following his remarkable U-turn which saw him leave the club in the dark as he opted to join Spurs instead at the last minute in January.
Spurs' injury list has piled up during the international break, making Cristian Stellini's task a little more daunting in his first game as caretaker since Antonio Conte's exit last week.
Wing-back is an area of great concern at the moment, as all three of their left-sided options are currently carrying injuries.
Ben Davies pulled out of the Wales squad with a hamstring strain which is expected to keep him out here, Ryan Sessegnon is still not ready to return and Ivan Perisic is doubtful, despite returning to training late this week.
Perisic hobbled off late on in Croatia's 2-0 win over Turkey in Bursa on Tuesday night after having his calf trodden on, but he may well be fit enough to start.
Davies's absence also leaves a hole in their back three, so Clement Lenglet may start again alongside Eric Dier and Cristian Romero.
Emerson Royal will be missing for around a month after surgery on a meniscus injury, meaning Pedro Porro should start on the right-hand side.
Rodrigo Bentancur is out long-term with an ACL rupture, but Hugo Lloris could return imminently after missing two months of action.
Yves Bissouma is also close to a comeback after surgery on a stress fracture in his ankle, but this game will come too soon for him.
Tottenham Hotspur possible starting lineup: Forster; Romero, Dier, Lenglet; Pedro Porro, Skipp, Hojbjerg, Perisic; Kulusevski, Kane, Son
