- John Stones (Everton to Manchester City; £47.5):
After the failures of Eliaquim Mangala and Nicolas Otamendi in the previous season, Pep Guardiola was in search of a ball playing defender right from the start of his tenure at the Etihad. With not much quality available in the transfer market, he decided to lure England’s youngest sensation John Stones to the club from the Merseyside. The 22-year old was superb for Everton last season and won the man of the match for a couple of games at the Etihad this season already making him one of the most important and also the second most expensive buy of the summer.
