Tottenham Hotspur manager Mauricio Pochettino has confirmed that Toby Alderweireld is likely to miss his side's Champions League clash with Bayer Leverkusen on Tuesday.

The Belgian was forced off in the second half of his side's 1-1 draw with West Bromwich Albion this afternoon following a collision with Baggies striker Salomon Rondon.

Pochettino is unsure as to the extent of the injury, but hinted that the defender will not be available for the midweek tie in Germany.

"With Toby we need to wait 24-48 hours. He got a heavy knock in his leg. We will see what happens, now it is very painful. We need to know the problem," he told reporters.

"It is very difficult [for him to go to Germany]. But we don't know, we need to assess him tomorrow with a scan or whatever the doctors want to do.

"I don't know exactly what happened, it was hard for me to see from the bench. All I said was, 'How are you?' And he explained he had pain. It is a big area - knee, leg, all."

Spurs needed an 89th-minute equaliser from Dele Alli to maintain their unbeaten start to the season at The Hawthorns.
