Watford goalkeeper Ben Foster labelled Diego Costa a 'filthy little rat' and former Manchester United defender Nemanja Vidic a 'sicko' in a hilariously frank interview.
The 37-year-old, who spent five years at United between 2005 and 2010, has come up against some of the world's best players in his career, having primarily played in the top-flight.
Foster is currently plying his trade in the Championship with Watford but has opened up on his days in the Premier League, naming his least favourite opponent ever, the biggest hardman and the worst trainer he's come across.
