The buildup to the summer transfer window has now begun, with rumours and speculation continuing to swirl as Real Madrid eye possible reinforcements.

Florentino Perez oversaw a significant overhaul of his squad during the summer before focusing more on youth in January. As is always the case with Madrid, though, some of the biggest names in football continue to be linked.

Here, Sports Mole rounds up the latest news of possible comings and goings at the Bernabeu.

Saturday morning's Real Madrid transfer talk news roundup:

Mikel Arteta 'keen to keep Dani Ceballos at Arsenal'

Arsenal are reportedly hopeful of securing a permanent deal for on-loan Real Madrid midfielder Dani Ceballos this summer.

Earlier this month, Gunners manager Mikel Arteta confirmed that the two clubs had opened talks regarding a possible long-term deal for the 23-year-old.

Ceballos initially struggled to nail down a regular spot in Arsenal's starting lineup, but the Spaniard has impressed in the middle of the park under Arteta since football in England was given the green light to resume.

Now, The Mirror reports that Arteta views Ceballos as a key player in his system, and the Gunners are optimistic about their chances of keeping the midfielder on the books in North London permanently.

Real Madrid president Florentino Perez recently admitted that Los Blancos are in a bad financial situation in the wake of the coronavirus pandemic in potentially a huge boost for Arsenal's pursuit as Madrid look to balance the books through player sales.

While the Gunners are expected to have their own financial difficulties in the transfer window, Ceballos could reportedly be available for a reasonable figure of £23m this summer.

Eden Hazard clauses to help Chelsea fund Kai Havertz deal?

Two clauses in the deal that took Eden Hazard to Real Madrid last summer could reportedly help Chelsea fund a move for Bayer Leverkusen's Kai Havertz.

The Blues continue to be linked with Havertz, and the Germany international has allegedly signalled that he wants to join Frank Lampard's side ahead of Manchester United and Real Madrid this summer.

Chelsea have already spent big on Hakim Ziyech and Timo Werner ahead of the 2020-21 campaign, but according to Sports Ration, the London giants could be set to receive a cash windfall.

The report claims that the £91m deal that took Hazard to the Bernabeu last summer included clauses that would be triggered if Los Blancos won La Liga or qualified for next season's Champions League.

As a result of the Spanish side's title success, Lampard's team are allegedly due to receive an additional £18m on top of the £14m they have already secured from Madrid's European qualification, which could help fund a big-money deal for Havertz in the upcoming market.

Chelsea are also thought to be weighing up a summer approach for Ajax's Nicolas Tagliafico.
