Close to CL qualification after three seasons? FFS, why? How is getting close to that an ambition fulfilled? Moyes got 4th and 5th; Martinez got 5th in his first season with a total that in any other season would have got 3rd never mind 4th.
Koeman is taking over a team that finished 11th twice, he also has to break a top 4 that makes on average 150m more revenue each season, its not going to be done overnight.
