Not for the first time in recent weeks, Tyson Fury has called out Anthony Joshua once again on Twitter today. However, boxing fans will be more intrigued to see he may have also dropped a big hint on who his first potential opponent could be in April. The 29-year-old has not seen action since the end of 2015 when he beat legendary Ukranian Wladimir Klitschko in a world heavyweight title fight. Since that victory, the 'Gypsy King' has been on hiatus due to a lack of motivation, mental illness issues and rehabilitation as a result of drug use.However, the British heavyweight is back in the gym and has significantly reduced his weight thanks to an improved diet and working with a new trainer. Fury is also under pressure to return action after being warned he risks losing his The Ring magazine world heavyweight belt if a fight isn't scheduled this month.Accompanied by an image of his entourage, Fury tweeted: "Tell me I'm not gonna take over the division once again! Wilder AJ Parker Charr watch out as the boggy man is coming for you! I'll see you in your nightmares! GYPSYKING WILL REIGN OVER THE WORLD."

Notice that, as well as the usual suspects Fury called out, he also included Manuel Charr.

Given how much Fury has spoken about Anthony Joshua, Deontay Wilder and Joseph Parker it was no surprise they were called out again but the inclusion of Charr is a little strange if there isn't something more behind it.

Charr is a 33-year-old Syrian-Lebanese heavyweight who has 31 wins from his 35 professional fights.

He supposed to fight David Haye in 2013 before the Hayemaker pulled out with a hand injury.

In November, he won the vacant WBA (regular) heavyweight title with a unanimous decision victory over Russian Alexander Ustinov.

Of course, only time will tell whether there is actually any substance to Fury's not-so-subtle hint but Charr would represent a potentially tricky rival for someone who hasn't fought for over two years.

Overcome that hurdle, however, and the likes of Deontay Wilder and Anthony Joshua will suddenly become far more realistic propositions.
