Tottenham Hotspur’s 4-0 win over West Bromwich Albion was soured by a nasty looking ankle injury to key defender Jan Vertonghen.

The Belgium international stretched to keep the ball in play in the second half and went over on his ankle, immediately knowing that his ailment was a serious one.

While the prognosis of how long Vertonghen will be unavailable for is yet to be released, Mauricio Pochettino must not change his approach with the former Ajax enforcer.

Tottenham are on a run of six consecutive Premier League wins, largely down to the fact that the North London side have switched to a 3-4-2-1 formation of sorts.

Although the temptation to revert to a back four in Vertonghen’s absence will be there, Pochettino should continue to play the system that has served the side so well in the last month.

Both Ben Davies and Kevin Wimmer are standing by to play in the Belgian’s role if required and although neither possess the 29-year-old’s authority or class, both have not let Tottenham down when called upon.
