The Italian striker is set to be sold by the Serie A club this summer.
Crystal Palace and Swansea recently joined the hunt for the player, according to Tutto Mercato Web.
However it is Southampton and Sunderland who are believed to be at the forefront of this chase. Gianlucadimarzio.com have reported that Southampton and Sunderland are very keen on signing the powerful striker this summer.
Now his club president has confirmed he is on his way out of the club. Massimo Ferrero is quoted by Fanta Gazzetta as stating:
"[AC Milan striker, Gianpaolo] Pazzini will not come, he can stay where he is. Okaka? He still did not want to renew the contract with us."
Okaka's current deal at Sampdoria expires in the summer of 2016 and the Genoa club are not set to allow him to enter the final year of his contract.
Okaka, who played for Fulham back in 2010, has played 33 times for the club this season, scoring just the four goals.
But when he first came to the fore at AS Roma he was considered one of the best young players around and this may be causing the interest.
It will be interesting to see which Premier League side wins the race for this much coveted commodity.
