But a reunion with their previous manager at Newcastle United is reportedly unlikely.
Two Newcastle United players are tempted to try their luck in their China, according to The Sunday People (page 55).
That is despite it adding that Shelvey is happier under Steve Bruce's management and in line for a new long-term deal at Newcastle.
The former Newcastle boss, Rafa Benitez, is currently in charge of Dalian Yifang in China's Super League - described by The Sunday People as 'cash-laden'.
But it is claimed that Benitez would not look for a reunion with the pair he managed at St James' Park.
It was the Spaniard who brought Gayle north from Crystal Palace, just months after Shelvey joined Steve McClaren's Magpies.
Shelvey and Gayle are just two of the Newcastle players out of contract at the end of next season, along with Matt Ritchie, Fabian Schar, Isaac Hayden, Ciaran Clark, Christian Atsu, DeAndre Yedlin and Henri Saivet.
