Tottenham Hotspur manager Mauricio Pochettino has said the ankle injury suffered by defender Jan Vertonghen in the win over West Brom "looks bad."
Spurs moved up to second in the table as Harry Kane's hat trick helped them see off the Baggies 4-0, but lost key defender Vertonghen after 64 minutes.
Vertonghen looked in pain as he hobbled off to be replaced Ben Davies, and Pochettino said: "It's disappointing for us, that situation. It looks bad.
"We need to wait until Sunday, Monday to assess better. He's disappointed. He's a very important player. We will push him to recover, we will try to help him.
