Sunderland boss Martin O'Neill says 'good luck' to cashed-up Manchester City.
The Northern Ireland tactician says he is ok with some clubs having a seemingly endless supply of cash with which to purchase players as it is simply part and parcel of modern day football.
"If you drop back to Chelsea a number of years ago, Chelsea had the spending power behind them and it yielded them the Premier League, they went very, very close in the Champions League a couple of times, and it proved worthwhile.
"Also, they had a fantastic manager in Jose Mourinho at the time, and Carlo Ancelotti carried that on last season.
"But Manchester City have taken it even to another level at the moment, and really, while these are the rules applying to the game, good luck to them.""It's just part of the game," O'Neill said.
