Tyson Fury is keen to return to the boxing ring as soon as possible and he is already calling out numerous possible opponents to herald his return to the sport.Fury has been blighted with fitness and personal issues since his November 2015 bout with Wladimir Klitschko, where he defeated the Ukrainian in Dusseldorf to become world heavyweight champion. Since that night in Germany, the 29-year-old has served a ban after it came to light that the Wythenshawe fighter had involved himself with substance misuse.But now, he hopes to resume his career, having submitted an application to regain his licence, so he can step his foot back into the ring.Should he be granted an opportunity, Fury has several opponents lined up to fight, including current champion Anthony Joshua.However, while sunning himself in Marbella, Fury uploaded a video to his Twitter account in which he challenged 46-year-old veteran, Shannon Briggs.Fury and Briggs have been linked to a fight for quite sometime now, and it appears that Fury is keen to get all the arrangements sorted sooner rather than later.The "Gypsy King" was of course as outspoken as always throughout the video and suggested that a contract offer is heading to the American - see the video below.Fury said: "This is a message to Shannon "The Cannon" Briggs. First of all, let's go champ."Second of all, I am going to send you a contract, get you signed up good and proper, so you know you've got something to train for."Keep yourself in shape, pump a bit of iron, do a bit of sparring, even come up and do a bit of training with me if you want."We'll get it on, there's a contract offer coming your way from me. Let's go champ!"

Of course, shortly after that, Fury posted another video to explain that he does not want Briggs to be his first opponent this year but would like to face the 46-year-old - and perhaps more bizarrely 49-year-old Antonio Tarver - at some point in the near future.

Like Fury, Briggs is usually pretty vocal on social media so keep your eyes peeled for a response!
