Roberto Martinez: Samuel Eto'o will give Everton fear factor

Samuel Eto'o will give Everton an unpredictable "fear factor" according to manager Roberto Martinez.

The 33-year-old Cameroon striker, who was a free agent after being released by Chelsea, has signed a two-year contract with Everton.

Martinez could hand Eto'o his debut against his former club on Saturday.

"When you see him on the team sheet you know the unpredictable play he has. Now we can enjoy the talent and that fear factor from Samuel," Martinez said.

Martinez said that Eto'o made a "football decision" to join Everton even though he had other options which might have been more lucrative.

"His emotional state and mental focus was impressive," added Martinez. "There is a real desire and hunger to achieve. He's desperate to create good moments in the British game."

Eto'o refused to be drawn on his relationship with Chelsea manager Jose Mourinho, who questioned the player's official age in private conversations broadcast on French TV.

But the forward insisted he was "physically and mentally in top form" and had "not felt better" ahead of a potential debut against his old club.
