Wenger readies Gunners for tough clash with Celtic

LONDON: Arsene Wenger has warned his Arsenal stars not to let complacency hand Celtic a European lifeline in today's Champions League playoff second leg.

Wenger's side have one foot in the lucrative Champions League group stages after cruising to a 2-0 victory over Celtic at Parkhead last week.

The Gunners' impressive display in Scotland means they don't need to win the return to go through. A draw or even a one-goal defeat would be enough to secure their place in Europe's elite club competition.
