Leeds United, Manchester City, Crystal Palace, Swansea, Sunderland, Newcastle, Southampton and Watford are reportedly interested in ex-Fulham loanee Okaka.
The 25-year-old has been on the books of the Italian outfit since 2014 and has a contract which runs until June 2016, according to Transfermarkt.co.uk.
“Leaving isn’t a life or death situation,” Beppe Bozzo told Sampdorianews.net, as translated by Football Italia.
“The player is open to the club for a contract renewal or extension, so it isn’t out of the question that he could stay at Sampdoria for longer.
“He certainly will not leave the Blucerchiati as a free agent. He wants Sampdoria, or a club of a similar level that is able to offer an adequate financial package.”
A number of clubs in England have been linked with Okaka, who played on loan for London outfit Fulham from AS Roma during the 2010-11 season.
Leeds United and Southampton are interested in signing Okaka from Sampdoria in the summer transfer window, according to Sampnews24.com.
Okaka scored four goals and created 27 chances in 31 Serie A appearances in the 2014-15 season.
The former Parma striker had a pass accuracy of 77% and a shot accuracy of 44%, and he won 26 headers, 38 dribbles and 18 tackles.
