This does not really outline the issues that Hughton has faced as manager of Ghana - both the international team and Ghana's domestic leagues have been a basket case for some time. This gives a small flavour of the mess Hughton has been trying to deal with -
https://www.theguardian.com/football...ribery-scandal
There has been serious issues with players refusing to play, bureaucrats demanding that certain players not be picked etc. Hughton was initially brought in as technical director to 'steady the ship' after the scandals - it was only later he was put in charge of the team. It is not a surprise that Hughton decided to work with Ghana - he father is Ghanaian - but (from what I heard) I don't think even he knew what he was getting himself into.
Ghana, as a football team, have been in a major slide since the scandals erupted in 2019 - that year they were eliminated by Tunisia in the Round of 16 in the AFCON - in 2021 they failed to get out of their group after failing to win a match. In the 2022 WC qualifiers they were very lucky to qualify for the play-offs and managed to win the play-offs on away goals. They finished bottom of their group. The slide has continued since.
What Hughton has done is steady the ship - after an anxious start to the campaign, they ended up qualifying comfortably - winning their two home games and drawing their two away games under Hughton. Yes - Ghana (ranked 60th) lost in the past couple of weeks to Mexico (ranked 13th) and USA (ranked 15th). They will have a tough time in AFCON in January - there are ten African teams ranked higher than them.
Now - what has been Hughton's experience in managing the team? Well Ghana have had an aging squad for some time - Andre Ayew is 33, Wakaso is 33, Mensah is 33 - and he has been trying to bring youth into the team. He has been trying to build the squad around younger players like Mohammed Kudus - who is going to be a monster for West Ham - Tariq Lamptey of Brighton, Alidu Seidu of Clermont (who Newcastle are after), Salis Abdul Samed of Lens and Antoine Semenyo of Bournemouth. Hughton expected to be spending most of his time in Europe watching and getting to know the players - but the same argument exists in Ghana as in Ireland about the domestic league - with the Ghanaian FA demanding Hughton spend more time in Ghana and pick players from a domestic league (still riddled with corruption). Hughton has also talked about the passionate fans of the Black Stars - but the fans can turn on the team in an instant when things go wrong and can be very intimidating (this has led to some players not wanting to play). The pitches the team has to play on are rock hard and covered in bumps - making it impossible for good teams to play a passing game (which is a reason why some of the higher ranking teams have difficulty against weaker opponents).
I have heard that Hughton intends to think about his options after AFCON - and whether he stays with Ghana appears to be an open question irrespective of anything else.
Last point - Hughton has never been too bothered about money - he was always one of the lowest, if not the lowest, paid manager in the PL. For him it has always been about coaching. This is not to say that he wouldn't expect to get paid - but he wouldn't be chasing money like, say, Robbie Keane - a guy who took €250K a year from the FAI for doing nothing - and is reputed to be on €350K a year in Israel.
Just that they don't just run all the rugby based adverts in isolation. They are listed on the websites of the IRFU, Leinster & Munster as official sponsors. If you are going to use a sport to flog your wares the decent and honourable thing to do is to provide some sponsorship for the people who organise it in your area. Walkers Crisps do something similar across the water with the Gary Lineker adverts and their sponsorship of Leicester City.
