This is all my opinion brother, Pirelli was a great sponsor due to what they are and no dodgy crap, however they paid us peanuts and it was embarassing for us as a top club, long contract at low money, basically I would say F*** Pirelli for how little they paid us for they years and years they graced our shirts, sponsors should pay so much more to grace our shirts and I do not say it as a fan I say it as a fan of italian football and what Inter brings to Serie A.
Moving onto the new sponsor, Socios.. Now I only know what reddit/discord/fif/a close friend source/websites and have taken what I believe from it, Socios is paying us €30m for 1 season to be on our shirt - people I believe are unhappy as to what they represent and how it looks on our shirt (I personally love the look, I personally couldn't care who they are as long as they bring money in to our club) the new sleeve sponsor etc I have only found out about yesterday and haven't researched anything.
A club like Inter relies on these kinds of sponsorships to make financial gains, we've done absolutely amazing this mercato however this isn't always the case, Inter are the kind of club to get grounded down by high wages to attract a high calibre type of player and most of the time its at the cost of them being to old to get excited about long term, its not always the case though.
Once again everyone has an opinion and make yours brother, my opinion on sponsors is zero fucks given, I just see it as financially helping my club and what grounds my thoughts are that Inter will have the best lawyers in the world and would have done their due dilligence on all sponsorships, if the sponsorships break the law, we remove them from the shirts and move on with our lives.
Hope this helps my friend and you are enjoying the FIF forums.
