Just another teenager wreaking havoc - that is his job, though

LONDON - Teenager Alex Oxlade-Chamberlain offered Arsenal fans a glimpse of a bright future as he became the club's youngest English goalscorer in the Champions League on Wednesday, netting the opener in his side's nervy 2-1 Group F victory over Olympiakos.

Signed for a reported 12 million pounds ($18.8 million) from Southampton in August, the 18-year-old is already being compared to Theo Walcott, who followed the same route to north London in 2006.

England winger Walcott was one of a number of Arsenal players absent through injury on a balmy night at The Emirates, but Oxlade-Chamberlain made the most of his first appearance in the Champions League, firing the opener after eight minutes.
