Tottenham key man faces spell on sidelines after serious injury

By Tony Hughes

Toby Alderweireld could be facing a spell on the sidelines after suffering an ankle injury in Tottenham’s 1-1 draw against West Brom on Saturday.

The BBC Sport live blog reported (4.18pm) that the Spurs defender was taken off the pitch on a stretcher midway through the second half at the Hawthorns after colliding with team-mate Jan Vertonghen.

It is said that Alderweireld appeared to have hurt his ankle before he was substituted and replaced by the versatile Eric Dier.

The potential loss of the Belgium centre-back would be a huge blow to Tottenham manager Mauricio Pochettino.

The 27-year-old has been a mainstay of the team since his transfer from Atletico Madrid in the summer of 2015 and has formed an outstanding central defensive partnership with countryman Vertonghen.

Spurs have conceded only four goals in the Premier League this season from eight matches and just one from open play, which was against West Brom on Saturday.

Alderweireld and Vertonghen are widely regarded as the best centre-back pairing in the Premier League and key figures in the club’s title challenge.

Spurs have dropped to third in the table after failing to beat West Brom, with Arsenal climbing above their bitter rivals following their 3-2 win over Swansea.
