The Bournemouth midfielder only joined the club from Leeds United in the summer.

Since leaving Leeds United things have not exactly gone to plan for midfielder Lewis Cook.
The youngster departed for Premier League side Bournemouth in the summer with the hopes of making it at the Vitality Stadium.
His exit was not welcomed by Leeds fans, who felt he was one of the best prospects to come out of their youth academy in years.

However, things have not gone well for Cook since his move to the Premier League.
Not long after signing Bournemouth then brought in a rather competitive rival for first-team football – with Jack Wilshere arriving on loan from Arsenal.
Now his season has taken another bad turn. He has suffered a serious ankle injury and may not be back in action until 2017.
Bournemouth manager Eddie Howe
Speaking to the Daily Echo his new boss Eddie Howe had this to say on Cook’s injury and recovery:
"Lewis is not going to need surgery, which is a really positive outcome. The specialist believed we could, potentially, get him back within three months.
"The fact he doesn't need surgery is a huge boost to him and us.
"The timescale was around the lines of what we were expecting but we were hoping he wouldn't have to go under the knife because then there are long-term implications with that."

Leeds fans will of course not wish any ill will on Cook. His exit was expected considering his talent and the troubles the club were having in tying him down to a new deal.
Cook, who has played just once in the Premier League for his new club, will hopefully get back on track in the new year.
