Daniel Sturridge became Liverpool's first purchase of the January transfer window and immediately promised he would "play anywhere" for his new club.
He denied claims he only moved to Anfield from Chelsea on condition he must be selected in a central striking role.
"I see myself as a striker. I think I perform best there because my attributes, I believe, are best as a central striker," said the 23-year-old, who has cost £12m.
"But I have played on the wing and have learnt a lot doing so. I would never refuse to play in that position and I've never demanded to play up front, either.
"For me, whatever the manager wants me to do I will do it and work as hard as I can for the club and the fans.
"I am humbled and happy to be here. Brendan Rodgers said he sees me here for a long time – and I also see myself here for a long time. I've not signed here to play for a couple of years and then move on.
"I've signed to be here for as long as possible. It's a humongous club – for me, one of the biggest in the world – and to have the fans and world-class players we have here is amazing.
"I'm just happy the manager has put faith in me. He is the first manager to actually pay for me and sign me, so I can't ask for any more from him or the club in bringing me here."
Sturridge's move to Liverpool is also good news for his former club, Manchester City, who will receive a payment as part of the deal.
City are entitled to 15pc of any profit from Sturridge's sale, a ruling of the tribunal which set his fee of an initial £3.5m in January 2010 for the move to Chelsea.
That figure eventually rose to £6.5m after additional clauses were activated when Sturridge played for England and made more than 40 first-team appearances.
It means Manchester City get around £825,000, equating to about a month's wages for Carlos Tevez. (© Daily Telegraph, London)
