Barcelona forward Neymar has insisted that the Spanish side will need to be at their best to overcome Manchester City on Tuesday evening.

The Catalan outfit travel to Manchester for the first leg of their last-16 Champions League clash this week.

Neymar, who made a scoring return in the 6-0 win over Rayo Vallecano in La Liga at the weekend, has predicted a "difficult" contest with the Premier League side.

"We played a good match and the build-up that ended in my goal was beautiful," he told reporters at a press conference.

"This victory gives us confidence for the difficult games ahead. During the season we've played some good games, but today we played one of the best games of the season.

"The game on Tuesday against City will be a very difficult match."

Neymar is expected to start on the bench on Tuesday following a one-month absence with an ankle injury.
