Samuel Eto'o will focus on improving his fitness during the international break as Everton prepare for a packed schedule of matches, coach Roberto Martinez said on Tuesday.

The Cameroonian striker, who joined Everton on a free transfer after leaving Chelsea in the summer, remains short of match fitness after picking up an injury during Cameroon's disappointing World Cup campaign.

He scored on his Everton debut against Chelsea after coming on as a second-half substitute but his side lost 6-3 in a thrilling English Premier League clash last weekend.

"That's a real bonus for us, to see Samuel already in such a good moment of form and making such a good introduction into his Everton career," Martinez said on the club's official website.

"He's fitted into the dressing room really well so I am really happy to see him have that big impact and we have to work extremely hard to get him up to speed so he can play 90 minutes in every game."   

Everton will play seven games within 22 days following the international break, with Eto'o likely to spearhead their attack.

"I thought he played with real experience, real know-how and you could see that every time he got involved in the action there was real meaning behind it," Martinez added of the 33-year-old, who was named Africa's best player a record four times.

"He really enjoyed his performance and his experience allows him to control the game well. He guided that ball into the net with real class."
