There's a few clubs where one or two losses to players will transform them from mid table to relegation fodder, Bournemouth being one of them. Southampton had a wonderful couple of years and lost everyone like Mane, Van dijk etc, and these clubs such as Brighton, Brentford, Bournemouth, start losing a couple of big players and it's could all go wrong. Mbwemo could leave Brentford, Semenyo and Kerkez could leave the Cherries, Brighton could lose Baleba, it will be interesting to see if any of the promoted sides (most likely Leeds) can replace any of those sides next year.
