9. Liverpool – Lucas Leiva
Debut: August 2007
Brazilian midfielder Lucas Leiva is currently in his 10th season with Liverpool after initially joining the club way back in 2007 when Rafa Benitez was in charge – he’s now worked under five different managers at Anfield including Jurgen Klopp.
It was apparently Klopp who stopped Lucas leaving the club this summer when a move to Galatasaray was ready to be completed, with the versatile 29-year-old seemingly still holding plenty of importance to the Reds boss as a squad rotation player.
