Shaqiri has signed a long-term contract with the Reds. The transfer fee was not disclosed, but media reported it to be 13 million pounds with release clause.

"I'm very happy that I'm here. I'm a player who wants to improve and this is the perfect place for me to help the team and help this club win titles," said Shaqiri in his first official interview at Liverpool.

The Swiss winger will wear the No.23 shirt, the same as his number at the national team.
