He got Ipswich to fifth in the PL and the UEFA cup. Unfortunately, since then he's taken some really crap jobs and not had much success with them.Thaumagurist*Royalee Burley - sacked by Ipswich, Hearts and Scotland, wouldn't be able to afford him and he wouldn't be able to do anything with this squad.
Sacked by Hearts? I may be wrong, but I seem to remember that he walked out on Hearts because he didn't like the interference from the chairman when it came to team selection.
By the way, he wasn't long at Derby either.
Still he has a track record at this level with Ipswich.
