Van Gaal won the league, domestic cup and CL with Ajax without taking an L thru all competitions...an entire season without Ls.
And won the eredivisie with AZ, so he did what Rainiri did with leicester before it was cool...also coached the national team to the semis...
Plus Iniesta said he was the most influential coach he had in his career, xavi, iniesta, muller,kroos, seedorf,kluivert etc etc up untill rashford all had their debute under his him... proven track record of making young players better...
Jose only coached clubs that are expected to dominate the league, lets see what he n pep can do if they would be in charge of a team like everton.
