Forgotten man Kieron Dyer is "positive" and "bright" about his hopes of reviving his West Ham career, manager Gianfranco Zola has said. The 30-year-old, whose spell at the top has been curtailed by a string of demoralising injury lay-offs, has recovered from his latest setback, a hamstring complaint which has sidelined him since the end of September, and could be brought back in against Burnley at Upton Park on Saturday. The former England midfielder has only started four matches for the Hammers since joining from Newcastle in August 2007 but managed two goals for the reserves in Tuesday's 5-2 win against Stoke. Zola insists Dyer remains a key member of the relegation-threatened Wrest Ham squad and will not be rushed back from his latest setback. "He's an important player and he's a quality player. It's good to have him back available," Zola said. "When Kieron Dyer is fit he can bring something different but what we don't want right now is more setbacks. "I don't want to put pressure on him. He's been out for a long time. I'm seeing him very positive, he's bright and he just needs to train a lot and be able to play to his standard for a long period."
