Everton boss Ronald Koeman says Zlatan Ibrahimovic is "still one of the best" as he prepares to face Manchester United on Tuesday but acknowledged he found the striker "difficult" when managing him at Ajax.
Ibrahimovic is set to return to the United side at Old Trafford after serving a three-match suspension, with the 35-year-old having scored 15 Premier League goals so far in his first ever season in England.
Koeman had managed the former Sweden international at Ajax, helping launch his career after a difficult start to life in the Netherlands, and said he has huge respect for his abilities.
