Celtic midfielder Landry N'Guemo has told skysports.com he is optimistic that Celtic can cause an upset at Arsenal next Wednesday.
Arsenal claimed a 2-0 victory in Tuesday night's UEFA Champions League play-off first leg clash at Parkhead.
SPL side Celtic have it all to do in the return meeting at Emirates Stadium, but N'Guemo is hopeful the Hoops could stun the Gunners.
He said: "We played against a great team. They can pass the ball with pace.
"They are very young and athletic, they dominated possession and it was difficult in the middle of the park.
"To be honest, their goals were very lucky, but they deserved to win.
"We can definitively score two goals away from home, so let's wait and see.
"The return leg will be difficult, not only for Celtic but also for Arsenal."
