Louis Saha admits that he has to be sensible and manage his calf injury as he nurses himself back to full fitness.
The striker has had a bad history with injuries especially during his three-and-a-half year spell at Manchester United which Saha admitted last month had affected him mentally.
However, the Frenchman seems to have put his injury problems behind him this term scoring nine goals in all competitions so far this season.
Everton manager David Moyes has been careful to manage the amount of football Saha plays and having picked up a slight calf strain in the Carling Cup defeat to Tottenham two weeks ago the frontman has had to limit his playing time.
Saha was withdrawn early in the second-half in the hard-fought 2-1 win over West Ham last weekend but the former Fulham man still managed to score with a sweetly-struck shot from the edge of the area to open the scoring.
"I have to be sensible with my calf strain. I do not want it to be damaged further by playing too long with it," he said.
"I tried my best in the game but I started to cramp in the second-half so it is better to be cautious and come off so someone fitter can come on."
