Frank Lampard's Chelsea will be relishing the challenge of a new season with new faces to bolster their squad.
The likes of Ben Chilwell, Hakim Ziyech and Thiago Silva are all still injured or lacking match fitness so the likes of Emerson, Ross Barkley and Andreas Christensen could impress if they get the call-up to cause a selection for Lampard in the coming weeks.
They face a Brighton side who will be familiar opponents - considering they had a friendly with their Premier League rivals just over two weeks ago.
A 1-1 repeat of that friendly will be a surprise to many and with thepools.com that is going for 7/1. The hosts are a respectable 9/2 but the visitors are the firm favourites at 4/7.
New recruit Timo Werner made his mark on English soil in a Chelsea for the first time in a Chelsea shirt at the American Express Community Stadium so it would fit the bill for him to score on his Premier League debut there too.
Albion are in a transition period after a number of big transfer decision were made in the summer. Coming in we have Joel Veltman and Adam Lallana who will bolster Graham Potter's side in defence and midfield.
Going out they have said goodbye to Aaron Mooy, Shane Duffy, Martin Montoya and Glenn Murray on both permanent and loan deals.
Four big and influential names in the dressing room will cause a dent in the dynamic while Chelsea's bolstering new squad will ignite the internal competition for places even more.
The hosts will be pleased to have Ben White on a new long-term deal after fighting off interest from Leeds United and with Kai Havertz and Werner looking to link up, it will be a case of when they will score.
