I'm with you on this one. I also think Moyes time here was an absolute disaster and set us back years, however I have trouble believing this.
Also how come this bit of news never came out at the time? From what I recall from the saga was Moyes was more interested in Fabregas, Kroos etc and Ronaldo was being linked with a return. Then when Pep became Bayern manager Thiago to Bayern seemed to happen very quickly.
My feeling is 'Dithering' Dave lived up to his nickname and started chasing difficult targets and ended up getting nobody apart from Fellaini.
