The Manchester Evening News, citing reports in Spain, says United are prepared to offer Casemiro "a wage packet close to that of top earner Paul Pogba in a bid to convince him to move."

Although United are reportedly very keen to bring the Brazil international to Old Trafford, PSG are also eager to sign him.

But both could face a battle to prise him away from Madrid, whose coach Zinedine Zidane has described him as a "fundamental" part of the Bernabeu squad.

No matter, says the Evening News -- Mourinho is ready to "sanction a wage packet that would make him one of United's top earners."

The Sun reports that the United boss is happy to push the boat out "in order to sign a player he rates very highly."

It adds that "during his time in Madrid, Mourinho worked with Casemiro and achieved La Liga glory, which is perhaps why he is prepared to offer him £290,000 a week."
