This is the beginning of a long, long fall for Southampton imho.
They'll have all of their best players leaving due to "breach of contract" issues or putting transfer requests in. No one will be wanting to stick around and be further connected with cheating. Although most, with even a shard of commonsense, will have had at least an inkling something a bit fishy was going on. The rumour that there's apparently a photo from Dec 2025 showing Salty Bill photoshopped as a sniper, which is alleged to have been circulated around squad members, suggests that it wouldn't have been hard to add things up.
Some of the players might even try to get money from them through legal means. It'll be interesting to see which if any do, as the club will probably try to claim that the players were complicit as a defence against this. A real old can of worms and the potential to be of huge damage to what little remains of the club's reputation. Also further damages their ability to attract signings...which has been squashed flat.
The FA will almost certainly be forced to take action against coaching staff, probably also management at the club if the evidence suggests they knew. And they will have known. Eckert will not have just gone off his own back to start doing this and even if he did at some point it must have been discussed at a higher level than him, especially if things like the 'sniper' photo were doing the rounds on WhatsApp accounts connected to the club.
The club and team will rightly get pelters from EVERY single fan base they play against next season. This will massively effect morale and impact hugely on the terraces. I doubt it can be much fun if every game is just a torrent of piss taking and abuse. And you best believe every team they play will be wanting their scalp as pay back.
You might see a seige mentality develop but it could just as easily create an enormous disconnect and gulf between the support, club owners and players. Add into the mix anymore potential claims of cheating from other clubs who feel aggrieved. This happens and theres a higher than average chance that Southampton could see more points deducted for the start of the season if complaints are upheld. Starting from -4 isn't the end of the world, might stymie a promotion challenge a bit but doesn't guarantee relegation either. Get a few more examples of cheating brought up and a -10 or more deduction added and you're fecked.
I cannot see Wrexham, and their Yank owners, being happy to accept whats happened thus far if they can find evidence to support a complaint. Other clubs are also threatening court action too including Hull who are keeping their options open if they don't win on Sarrada.
While I have sympathy for the fans, a visible proportion of them seemed to be revelling in it! I doubt they're finding it as amusing this morning.
