OPINION By Tottenham correspondent Tony Hughes

Mauricio Pochettino is expected to once again ring the changes for Wednesday’s Premier League clash against West Ham as Tottenham continue to navigate a busy fixture list.

The arch-strategist manager will have half an eye not only on the trip to Upton Park, but also the pivotal north London derby against Arsenal on Saturday.

With injuries starting to be a factor for a squad who have stayed clear of them for so long, these two derbies in four days will tell us whether this mightily impressive Spurs team have the staying power to keep churning out the results.

Mousa Dembele (groin) is unavailable once again, but Tom Carroll is fit again and Pochettino could give a breather to playmaker Dele Alli, who has started the last five matches.

Alli struggled with an ankle injury against Swansea and, if he passes a fitness test, it would be sensible to drop him to the bench and bring him on as an impact substitute if needed.

Ryan Mason, Kieran Trippier, Ben Davies and Nacer Chadli will come into contention to start at West Ham after being on the bench for the last-gasp win over on Swansea, while Erik Lamela could get the nod over Heung-Min Son.

Tottenham (possible): Lloris, Trippier, Alderweireld, Wimmer, Davies; Dier, Mason; Lamela, Eriksen, Chadli; Kane.
