Everton have been dealt a massive blow with the news that influential midfielder Steven Pienaar will be out for up to a month with a injury sustained in training.
The South African midfielder missed out on the 1-0 victory over Chelsea at the weekend, and the club's medical staff have now revealed he will be out for longer that first expected.
The Everton man is likely to miss four games for the Merseyside outfit, however it could have been more had it not been for next months international break.
Pienaar will be absent from the away trips to West Ham United and Manchester City in the Premier League, the home game against Newcastle United and the League Cup match away at Fulham.
Arouna Kone, who also missed the win against Chelsea, is likely to make a speedy recovery.
Martinez told Evertontv: "I think Steven Pienaar is going to be a little bit longer - it's a grade one soft tissue problem. But Arouna Kone shouldn't be too long."
Meanwhile, Everton new signing Gareth Barry impressed on his debut for the club after joining on loan from Man City on deadline day.
Everton remain unbeaten so far this season, but goals look hard to come by. The club lost two of their top scorers from last season, Marouane Fellaini to Manchester United, and Victor Anichebe to West Brom.
Steven Naismith scored the decisive goal at the weekend, but his strike partners Nikica Jelavic and Arouna Kone have so far failed to hit the back of the net.
Martinez continued: “The goalscoring ability of a team is one of the biggest points in being able to be successful.
“I don’t think when you rely on one player you are going to be successful in the long-term.
“Clearly in the first three games we have not scored enough goals, apart from the Norwich game obviously.
“But we have been having opportunities and I like the way we have been controlling games. Now the work is to have enough goals in the side."
He added: “I don’t think we can rely on one person, to rely on one player to score you 25 goals."
“Those players don’t exist, or if they exist they will move on after 10 months because that is the market forces."
“We need to be able to score goals from all over the park and share the responsibility, and rely on our pattern of play to score goals, not on individuals or dead-ball situations."
“That is where the work is.”
