Arsenal manager Arsene Wenger has questioned the motives of the Abu Dhabi United Group in their multi-million-pound takeover of Manchester City.
The arrival of the Middle Eastern billionaires has changed the balance of spending power in the Premier League as Arabian chief Sheikh Mansour bin Zayed Al Nahyan will formally become the new owner of the Eastlands club on Tuesday.
However, Wenger maintains the reason behind the unexpected developments in the City boardroom remain a mystery.
Speaking in the October issue of the official Arsenal magazine, Wenger said: ''I don't know why these people are in there.
''It doesn't look like they are there to make any money. So if they are not there to make money out of it, then are they buying it out of love? Well, I am not sure these people are supporters of Manchester City from a young age.
''So then comes a further question: Why are they doing it? Why have they bought the club? I can't really find a rational answer.''
Wenger added: ''If it is just a toy for them then it is even more dangerous.
''You can have 20 billionaires in the Premier League, still only one can win it and one will come last.
''The problem is that when these people who have bought into football get tired of it, what will they leave behind? That is the real question you can ask.
''If their investment is purely strategic, based on the market interest, then they could easily decide one day that it is not strategic to be in that market any more, and then they will leave.''
