4) Bob Bradley (Swansea City) – 84 Days
The 2016/17 season was a pretty chaotic one for Swansea. They had sacked Francesco Guidolin after only 25 matches in charge before turning to Bradley.
Nobody expected the American to be in the running for the job and he was very much a left-field candidate.
Bradley failed to convince the locals, and the game was up pretty quickly, having secured only eight points in 11 games.
