Barcelona striker David Villa says he will work hard to break his goal drought in the Champions League on Wednesday night against Shakhtar Donetsk.
Villa, 29, became Spain's leading scorer when he netted his 45th and 46th goals for the world and European champions against Czech Republic last month, but hasn't hit the net in six games for his club.
"You always get a bit worried when you aren't scoring but you have to stay calm," Villa said. "I know it's been a while since I scored, but the only way to put that behind me is to work hard in training and on the pitch.''
Barca coach Pep Guardiola has been boosted by the return of forward Pedro and full-back Maxwell, but captain and central defender Carles Puyol is still not fit for the clash.
Meanwhile, Shakhtar striker Eduardo has been passed fit to face Barcelona.
Eduardo was left out of the side as the Ukrainians beat Mariupol 3-1 and went 12 points clear of Dynamo Kiev at the top of the Ukrainian league table on Friday, but manager Mircea Lucescu claims he is ready to return.
"In the past two days, he has worked with the main group and trained well," Lucescu said. ''It seemed that the players were thinking about Barcelona. It was important we won the three points to keep our distance in the league. Moreover, we enthusiastically prepared for Barcelona."
