I seem to recollect that Samaras became a living legend in Scotland but not quite so in England. It is a huge step up to the PL. It is also more difficult for anyone playing CB. If Iheanacho misses a sitter no one will mind particularly if Aguero gets a couple and we win. If a young centre back makes a mistake and costs us the game then he will get a lot of criticism from some. Best to get good experience playing competitively at a slightly lower level first. There is no rush and we can be patient. I would think it fairly obvious the decision was taken collectively by the club and not just by Pellegrini and would not be the least bit surprised if the same decision would be taken today.
