Rafa's best time was ironically with Valencia, not Liverpool. With Liverpool the only trophy that was major was the CL which was pretty much a Chelsea'sque win. Maybe he has plied his trade with more clubs but rating him over Pep makes no sense.
Sure Pep has only coached one club... but the changes he brought to the game is the reason he is so sought after. Besides winning the phenomenal amount of Sliverware, he made the whole world go abuzz with what you refer to 'the Barca Style'... which ironically is being tried to be incorporated in many major clubs including Liverpool
So I really wouldnt take Pep's influence and quality as lightly if I were you... and if you followed Pep he also said that the next team he coaches will not be another Barcelona... the Barcelona Style worked because it was the Barca Style... with whichever club he coaches next he will work in incorporating and cementing their own style and philosophy which will take time...
Rafa has done enough to justify his 2 years at Valenica winning 3 major trophies and his first 3 years at liverpool before the 2 american dicks came over.
in his first season , he lost the carling cup final narrowly to chelsea to a own goal in the dying minutes of the final, won UCL, super cup and lost in the world cup club final in one of the most one side finals but yet lost, the no of chances wasted in that game cant be counted on 2 hands
next season we beat chelsea in the community shield ,won the fa cup as well all this without a decent striker.
then guess who came over yet we reached the UCL final again after that the problems started yet we finished second in the following year,
rate pep over Rafa at ur own risk,give pep the team rafa had in his 3 years at liverpool and or 2 years at valencia and see what he does,
Rafa is a master at overachieving with what little he has maximising the use of whatever he has,
pep was blessed to have the likes of messi, inesta, and xavi,plus whatever funds he needed to buy players he liked,but it will be hard to repeat what he did there unless he is give a lot of time
before pep it was Rijkaard on evryones lips ,winning every trophy in sight and making him dream manager for everyone, where is he now?
