Mourinho, meanwhile, has been disappointed in his hopes of landing one of his former Real Madrid players. Elsewhere, according to reports, Arsenal are facing competition from a major European name for one of their transfer targets.
And who is the latest name to be linked with the new era at Old Trafford under David Moyes? Read on to find out more.
Lewandowski had appeared to be following Mario Gotze to Bayern Munich when outgoing Allianz Arena coach Jupp Heynckes revealed the Poland international would soon join the Bundesliga champions, as ESPN reported.
However, Dortmund chief executive Hans-Joachim Watzke insisted in an interview with German newspaper Bild that the forward will not be joining Bayern this summer, as Luke Edwards of the Daily Telegraph reported.
Manchester United were linked with a move for Lewandowski earlier this season, as John Edwards of the Daily Mail reported in April.
And now Old Trafford manager David Moyes has been credited with renewed interest in the 25-year-old in the wake of Watzke's words along with Chelsea and Arsenal, as Simon Rice of The Independent highlighted.
But Juventus are determined not to let the 25-year-old move to the Premier League without a fight and The Sun reports that Real president Florentino Perez met with his Juventus counterpart Andrea Agnelli recently at the Bernabeu.
The future of Higuain will ultimately depend on the identity of the new Real manager following the departure of Jose Mourinho, with Carlo Ancelotti likely to replace the new Chelsea boss, as The Guardian reported.
Cavani says he would be happy to play under Jose Mourinho at Chelsea or Manuel Pellegrini if he takes over at Manchester City, as Sky Sports reported, paving the way for the West London club to make their move for the Uruguay international.
The Croatia international joined Real Madrid and Mourinho for £30 million last year, but has not made a significant impact on the first team at the Bernabeu.
However, according to a report by Rob Beasley in The Sun, the returning Chelsea manager targeted Modric for a move to Stamford Bridge.
But the 27-year-old insists he wants to stay with the La Liga giants and make his mark under the new manager who replaces Mourinho at the club.
