Mikel Arteta's knee operation has been deemed a success by Everton.
The midfielder underwent surgery in his native Spain on Tuesday after suffering a cruciate knee ligament problem in last month's goalless draw with Newcastle.
Arteta faces up to six months on the sidelines with the problem and Everton physio Mick Rathbone insists the player is in good spirits after one of the Blues' other backroom staff, Matt Connery, travelled with Arteta to Spain for the operation.
"Matt told me that the surgeon is extremely pleased with the procedure and that it couldn't have gone any better, which is great news," Rathbone told the club's official website.
"Importantly, Mikel himself is also in very good spirits."
