As Nick Kyrgios has relaxed with friends and family, away from the eyes of the world, his manager has been "sifting through" sponsorship offers from companies keen to cash in on the Wimbledon world-beater.

UK-based John Morris returned to Canberra with Kyrgios on Sunday to navigate the influx of offers after his young charge rose to world prominence, beating world No.1 Rafael Nadal on Wimbledon's centre court.

Morris' phone has been ringing hot with companies keen to associate with Kyrgios.

Cars, watches and drink brands are all keen for the 19-year-old to spruik their goods, but he isn't looking to cash in just yet, and Morris is taking a discerning approach to his young charge.

"Nick's quite a down to earth guy; he's not somebody who would endorse something he didn't believe in either," Morris said.

"We're not looking for short term gimmicks …  we're looking for partnerships with people looking to come on board and be part of the Nick Kyrgios brand and the Nick Kyrgios journey, and that's why we're being very selective in a sense of who we partner with and who we bring into that team."

Morris is also wary of overcommitting Kyrgios to sponsorship agreements for the sake of more bucks.

"Nick's far from the finished article yet, he has a long, long way to go, and it would be foolish to enter into agreements or partnerships chasing dollars as opposed to really focus on improvement and being the best he can be on the tennis court,'' Morris said.

Adding to the flood of offers is Kyrgios' big on-court personality and his grounded family life which make him so marketable.

"If you look at Nick on the court, he's a showman, he's charismatic, he's entertaining, exciting, he plays high-risk tennis and he's got this nickname of 'Wild Thing' and he's got this edgy look and he's very aggressive on the court," Morris said.

"But off the court … he's very grounded, very humble, very much a home bird."

It's that low-key off-court life which differentiates Kyrgios from fellow Australian up-and-comer Bernard Tomic, and Morris doesn't expect Kyrgios to be driving a sports car around Canberra in the near future.

Kyrgios took a low-key approach to getting back on the court too, with a light training session at the AIS in Canberra on Tuesday to blow out the cobwebs.

"Nick's very different from Bernard – they're friends, they get along very well … but they are very different people, they've got different aims and different ways of doing things and it's not something Nick would get into in a sense.

"That's just not Nick, it doesn't mean Bernard's in the wrong, just what floats Bernard's boat doesn't necessarily float Nick Kyrgios' boat."

Kyrgios is expected to announce a change in his coaching arrangements on Wednesday, citing the desire to spend more time in Canberra with his family when he's not touring than he currently does working with Melbourne-based coach Simon Rea.
