He most certainly didn't keep us away from the relegation zone. In his first season we finished 15th, winning just 9 games out of 38, the same as 17th placed Aston Villa. The season after was even worse with the same number of wins and 16th place. Burnley in 17th won a game more than we did.
The above - and the fact that most of the non-wins were at home - is exactly why I don't like him. Looking at the bloke's record objectively he's had one good season in the UK. Finished mid table with Swansea in the Championship. 15th and 16th with us, 9th (admittedly decent) and then sacked by Chelsea mid-season for, erm, not winning games.
Completely agree with this. We were so patient during the ridiculously long barren spells and the predictable "horse shoe of death" football we played in the final third. In return we got smart-arse comments about "history lessons" before he left us completely in the lurch when it suited him.
