Winning the league with Ajax and having one good run in the CL. I am scoffing at it, the same way you are scoffing at McKenna even though many managers with no prior experience have gone on to win plenty off things. Alonso, Zidane, Pep did not have experience either, and they were great.
Cool, but still shit. The point of management is not to shit the league and end up 8th. All that pedigree and experience means feck all. It has not helped ETH in the league. Alonso, Arteta, Pep, Zidane did well with none of that. McKenna has plenty of talent, and you have no clue how he will do here. Also, he knows us better than even ETH, so I think he knows plenty about the challenge.
