Arsenal boss Arsene Wenger is confident an injury suffered by Tomas Rosicky against Red Bull Salzburg this week isn't serious.

The Czech Republic midfielder limped off just after the half-hour at the Bulls Arena, seemingly in some discomfort.

However afterwards Arsene Wenger played down any fears.

"We don't think it is serious," said the manager. "He had a tight hamstring and we did not want to take a gamble."
