Barcelona coach Pep Guardiola has admitted that he's expecting a tough tie when the La Liga champions take on Arsenal in the Champions League last 16.
Guardiola's side knocked the Gunners out of the competition last season although the Spaniard knows the task of advancing past Arsene Wenger's side will not be easy.
"The defeat against Betis will help us to grow, in about three weeks we play Arsenal, and this will not be easy. But in spite of this, I remain positive for the second half of the season," he said after Barcelona's 3-1 second leg defeat to Real Betis in the Copa del Rey.
"They [Betis] are leaders in their league, where they have very good players, who have aspirations to reach the first division. They have talent to spare."
Guardiola also warned his side that while they have forged a four-point lead in the title race, nothing is decided at this stage of the campaign.
"The title is never won in January or February. The defeat we suffered is a demonstration of what can happen in sport. It gives value to what we have done already," he concluded.
