Uruguay international Suarez was excellent in the first half of the season, but he has been rather less effective in front of goal since then, and that is reflected in Barca's form, having now drawn four of their last five games in all competitions.

Suarez was lively in France against Lyon in the opening leg of their last-16 clash, sniffing out a few opportunities, but his finishing left a lot to be desired and he looked visibly frustrated on numerous occasions on Wednesday (AEDT).

It was the fifth game in a row Suarez has not scored in, while he passed 24 hours of playing time in the Champions League without an away goal in the 22nd minute.

Barca head coach Valverde is not concerned, however.

"I would worry if he did not generate scoring chances, which is what is asked of a striker," Valverde told reporters.

"He always has chances and if not, he generates them and is a headache for the rival. And, in any case, he is linked well with the occasions we've created.

"Football is a matter of success. If the opposition wastes occasions I get nervous; if we waste them, it only bothers me."
