I think Rafas stock in England isnt great anymore, hes looked down as a failure at Liverpool by all(part from Liverpool fans who remember him fondly for the CL win/final), as they fell apart abit in his final season and ever since then.
Hes laughed at for his terrible performance at Inter where he was sacked only 4-5 months after they won a treble, and they have basically been rubbish ever since.
I guess the worry for Chelsea fans is he could do the same to us... we won the CL and the FA cup last season and although we could yet win the EL and get top 4, we could equally as likely win nothing and end up 5th-6th... and then suddenly we cant attact the best players anymore(i.e falcao), and keeping hold of our stars is made even harder(they want CL football). Suddenly you are into the same situation Liverpool are in, having to buy younger players who are unproven and maybe not good enough for top 4/CL football.
Although Rafas stock in Europe is still high, i think he will get another top job in Spain very easily, even rumours he could be replacing Jose at Real Madrid(and may well happen if he wins us the EL/top 4). Although rumours Real want AVB/Ancelotti too... All ex Chelsea coaches..
Im still undecided on Rafa, and thats the worst point, hes kept us chugging along but never really impressed yet. His results have been steady but nothing too impressive and a few dire losses/draws. He has to win the Europa League/ Get top 4 if he wants to impress me, and im sure most Chelsea fans will think the same.
