(Reuters) - Arsenal manager Arsene Wenger is wary of over-working striker Danny Welbeck because of fears the England striker could suffer a set-back having recently returned from a long-term knee injury.

After three substitute appearances, Welbeck marked his first start of the season by scoring two goals in Arsenal's 5-0 win over Southampton in the FA Cup on Saturday.
