But the defender's rehabilitation has not gone to plan and he is expected to be out for longer than initially anticipated.

Meaning he is also expected to miss the North London derby at the Emirates on the November 6th.

But now Belgium are also concerned as there are fears he may not be ready to compete in their international fixtures against Holland and Estonia in November.

It's expected that Pochettino's trusty midfielder Eric Dier or defender Kevin Wimmer will step in for Alderwiereld as Spurs look to maintain their unbeaten start to the Premier League.
