Albion take on Chelsea at the Amex tonight (8:15pm, Sky Sports) in their opening Premier League game.

However, just where will the key battles take place that could help to decide the match.

Well below are the five battles which could prove decisive:

Timo Werner v Adam Webster, Lewis Dunk and Ben White:

The Chelsea striker got the better of Webster, Dunk and White in the friendly at the Amex a couple of weeks ago, after opening the scoring in the fourth minute.

If the Albion back three can keep the free-scoring German striker quiet this time round they could be on course for a clean sheet.

Solly March v Mason Mount:

Mount was a key figure for Chelsea in Frank Lampard’s first season at the club, with the England international scoring eight goals and getting six assists in all competitions.

The 21-year-old started a lot of the games on the right-hand side of a front three last season for Chelsea but was known to drift inside, so whoever plays left wing back out of March and Dan Burn could have a tough evening.

If Potter were to go with March like he did in the final pre-season friendly against West Bromwich Albion, he will have to keep a close eye on Mount to make sure he has as minimal involvement for Chelsea as possible.

Neal Maupay v Antonio Rudiger and Kurt Zouma:

Maupay could again be heavily relied on by Albion to score the bulk of their goals again this season.

The French striker got ten goals in his first season in the top flight.

However, if Albion are going to get anything from the game they will need him to be able to take his chances against Chelsea.

With new signing Thiago Silva not available it will probably be left to Rudiger and Zouma to keep an eye on Maupay and they will need to be on top of their game to keep him quiet.

Tariq Lamptey v Kai Havertz:

Chelsea’s newest signing and their most expensive of the summer Havertz is set to get his first taste of the Premier League.

If he starts the German forward could well end up on the left of a front three, which would mean it would be up to Joel Veltman or Lamptey at right wing back to mark him.

Potter tended to play Lamptey as a wing back towards the end of last season and if he continues that trend tonight, then the former Chelsea youngster will be hoping to put in an impressive performance to further cement himself as one that got away for the Blues.

Leandro Trossard v Reece James:

Trossard was on fire for Albion after the restart and started to show the form he had at the beginning of last season.

He picked up both his goals after the restart with finishes in the box after drifting in from the left wing.

He will have a tough battle with Chelsea youngster James set to be up against him.

The 20-year-old full-back impressed for the Blues last season to force Cesar Azpilicueta to play at centre-back rather than the right back position he is more accustomed to.

If the Belgium winger can get the better of him, he could pose some defensive problems for Chelsea.
