5. Danny Care
The scrum-half signed a two-year extension back in 2019, meaning he will be out of contract next year. Care, who currently earn £300,000 per season, has won the Premiership (2012) and the European Challenge Cup (2011) since joining Quins from Leeds in 2006.
The 33-year-old is attracting interest from Major League Rugby franchise San Diego Legion, who have already signed Chris Robshaw, but is reportedly keen to remain in London with ambitious club Ealing Trailfinders identifying him as a possible target after missing out on Richard Wigglesworth.
