West Ham face Chelsea this weekend at The London Stadium hoping to build on their momentum.

The Hammers are off and running in the Premier League after beating Everton at Goodison Park last Sunday.

After losing the first four league games, the 3-1 win over the Toffees was much needed.

But this Sunday, Chelsea are a very difficult opponent. The Blues have won all five of their opening games under new manager Maurizio Sarri.

Here are three danger men that West Ham need to be wary of this weekend.

Marcos Alonso

Alonso is an attack-minded full-back who will cause West Ham problems coming forward.

Last weekend, the Hammers were vulnerable when Lucas Digne bombed on from left-back and Alonso will hope for similar attacking joy.

But this could leave gaps at left-back and we all saw what Andriy Yarmolenko can do when given a bit of space.

Ngolo Kante

Kante is widely renowned as one of the best defensive midfielders in world football.

The France international moves from side to side, sweeping up any attacks and then taking the ball forward.

West Ham will look to match Chelsea’s three in midfield but Pedro Obiang and Mark Noble will have their work cut out trying to get past Kante.

Eden Hazard

This is without doubt the major danger man at Chelsea. Hazard has had an extraordinary start to the season.

With five goals (and two assists) to his name so far this season, the Belgium international is the top marksman in the league.

Hazard possesses skill, pace and a real eye for goal. West Ham will need to keep him quiet to have any chance of winning the game.
