The former Bayer Leverkusen forward has moved to England on a free transfer after coming to the end of his contract in Germany and will be competing for a place in Rafael Benitez's side with another new signing, Fernando Torres, as well as Dirk Kuyt, Peter Crouch and Craig Bellamy.

But the 27-year-old, who agreed a four-year contract with Liverpool in February, appeared unfazed by the prospect of fierce competition for starting places.

"I have not made this decision just to sit on the bench," he said. "I have come to get in the team and form a partnership with someone."

Voronin was part of Ukraine's 2006 World Cup squad and has won 44 caps. He has spent all of his senior career in Germany, playing for Cologne, Mainz and Borussia Monchengladbach before joining Leverkusen.

Benitez said he was confident that Voronin would enhance a Liverpool squad aiming to mount a serious challenge for the Premiership title next season.

"He is a player with pace and with good movement," Benitez said. "He plays between the lines, between defenders. He is a good worker also, and he scores goals.

"He's not the kind of player you can talk about strengths because he has many things he can give to us."
