Guardiola, who will replace Manuel Pellegrini at Manchester City this summer, won three league titles with Barcelona and recently won his third Bundesliga crown with Bayern Munich.
However, he leaves Bayern without a Champions League trophy after three exits at semi-final stage and The Sun’s Kastrinakis believes his transfer record should be of concern to City fans.
“If you go to Bayern pretending you are the best thing since sliced bread and you are on 17m or 18m euros a year, you have to deliver,” Kastrinakis said on the Sunday Supplement. “He believes his own myth and that’s a shame.
“If you look at his signing record at both clubs, but Barcelona in particular, you can see he wasted hundreds of millions and people don’t realise that. On people like Zlatan Ibrahimovic – they took a 40m euros hit in one season – and others like Dmytro Chygrynskiy.
