Manchester City are hoping highly-rated defender Mehdi Benatia will force AS Roma to let him move to the Etihad.
According to the Sunday Mirror, Benatia has told his current club that he wants to join City, but Roma are now asking for treble the initial asking price.
Roma sporting director Walter Sabatini said: "Benatia is not for sale, unless someone comes to us with an offer of 62million euros.
“Personally I think 31m euros is the value of Benatia’s weak foot. In that case the total price would be 62m.”
The £50m valuation could be a stumbling block though, as the main reason Pellegrini is pursuing the Moroccan is after Porto slapped a £40m price tag on prime target Eliaquim Mangala.
City have also been hit by a £50m spending cap as a result of their breaching of Financial Fair Play.
However, Benatia believes Roma to have gone back on a promised pay-rise and will now look to force a move to England.
If the deal does come to fruition, he is set to earn £80,000 and could become the most expensive defender in the world.
