Pep had the greatest side though; Basquets, Xavi, and Ineista were nowhere their best when Enrique was there. I am not saying he is better than Pep, give him the resources he will implement a side that will be at the very least competing for PL. I do not care for his results at Roma and Celta, we are not trying to hire a manager for their level. Potter is a good example, he was doing well at Brighton but it is different level for clubs like Chelsea. What was Carlo track record at Everton and Napoli(better side than Roma)?
He has experience winning the league and CL. Look at the success of Xavi, Arteta, and Pep it is quite clear such football produces the best football in combination with winning.
Who do you want?
