The transfer of Christian Atsu from FC Porto was completed on 1 September 2013. The 21-year-old Ghana international signed a five-year contract and joined Vitesse Arnhem on loan for the season.
Atsu is a left-footed attacker, capable of playing as a winger or a second striker, and joined Porto from Cheetah FC in his homeland in the January 2010 transfer window.
He quickly won individual and team youth honours including Porto's Youth Player of the Season for 2010/11. That year he was named on the bench for a first team game by Andre Villas-Boas but was not called into action.
The 2011/12 season was spent on loan at Rio Ave, also in Portugal, where Atsu made 30 appearances in league and cup and scored six goals, earning him the club's Player of the Season award.
Breaking into the Porto first team last season, he made 17 league appearances as the club won the Portuguese championship, and he gained European experience with eight Champions League games, including a Round of 16 tie against Malaga.
Atsu made his debut for Ghana in June 2012, scoring against Lesotho in a World Cup qualifier, and became regular. He played and scored in the Africa Cup of Nations at the beginning of 2013.
