Despite a 2-0 win at Arsenal in the first leg, Barcelona forward Luis Suarez's remains wary of the Londoners.
Luis Suarez knows Barcelona's Champions League last 16 tie against Arsenal is far from over, despite a comfortable away win Tuesday.
Lionel Messi scored two second-half goals as title holder Barca defeated Arsenal 2-0 in the first leg at the Emirates Stadium in London. However, Suarez remains wary of Arsenal heading into the return leg, with the English side's quality not to be discounted.
"We are very happy as we got really nice score but we know that it is still not done," the Uruguay international said.
