Ronald Koeman has hailed Lionel Messi as he closes in on Pele's one-club goal record, while expressing his belief that the world will never see another player like the Barcelona captain.
Messi, who continues to be linked with a Barca exit although hasn't yet held any discussions with other clubs, has scored a staggering 642 goals in 746 appearances for Barca since making his senior debut back in 2004.
The 33-year-old has set a mark as the club's all-time leading scorer which will likely never be broken, while winning a whole host of honours on both team and individual levels, including four Champions League crowns, 10 La Liga titles and six Ballon d'Or awards.
