The quiet, family Championship club will undoubtedly succeed in making a big noise and should also be able to win promotion next season.
But it is likely to come at a serious cost. The turnover of players at Sunderland under Keane was astounding and the cost of ?80m in 15 months was eye-watering too.
Man's best friend: Roy Keane walking his dog has been a common site in Cheshire
[columnistModule] The former Manchester United midfielder signed 33 players in his short time at the Stadium of Light plus three more on loan. He also got rid of 25 and stability in the Sunderland squad looks a long way off in the wake of his departure last December.
Money and a big name should draw players to Ipswich too but how long the supplier of the promised cash and his fiercely independent and combustible manager can get on is another matter.
Ipswich are changing their whole ethos for Keane, shooting for the stars and eschewing the conservative approach that historically brought them success.
Maybe to get up to the Premier League it is worth it, regardless of the state Keane leaves the club in when they are up there.
But it is interesting that Ipswich have only given him a two-year contract. They had better start planning for the day he leaves now.
