Italian champions Juventus are reportedly ready to tighten their grip on Arturo Vidal and Claudio Marchisio.
According to Tuttosport, the midfield duo are being looked at closely by the likes of Real Madrid, Paris Saint-Germain and the two Manchester clubs.
It is also understood that Juventus turned down a multi-million Euro offer for the two men from Bayern Munich in the summer.
Aware of the interest in the pair, director general Beppe Marotta is willing to offer the men new improved contracts in Turin until June 2018.
Vidal, signed from Bayer Leverkusen in the summer of 2011, and Marchisio are committed to the Old Lady until June 2016.
Marchisio earns €3m a season, while Vidal is on €2.7m a campaign.
