Tottenham are again sweating over the fitness of Dominic Solanke after the striker appeared to pick up a fresh injury in the defeat at AZ Alkmaar in the Europa League.

The striker made his return after seven weeks out with a knee injury suffered in training, coming on with around 20 minutes to play as Spurs pushed for an equaliser.

With the game heading into injury time, Solanke jumped to reach a cross, collided with Rome-Jayden Owusu-Oduro mid-air and fell to the pitch on his left-hand side.

Solanke immediately looked in pain, clutching his side, and was unable to continue. He was quickly replaced by Dane Scarlett and helped from the pitch and down the touchline.

It is potentially another huge injury blow for Spurs, whose crippling injury crisis is starting to finally ease and now face an uphill task to reach the Europa League quarter-finals after losing 1-0 to Thursday night's last-16 first leg.

Speaking after the game, manager Ange Postecoglou said: “We think it’s a knock, so hopefully nothing too bad. He’s a bit sore.”

Spurs’ season rests on their Europa League campaign having been knocked out of both domestic cup competitions while their Premier League form has seen them languish in the bottom half for months.
