Atsu, who joined Porto in January 2010 from native side Cheetah, mainly operates as a left winger but can also play as a supporting striker.

The winger, who was Porto's Youth Player of the Season in 2010/11, broke into the Portuguese outfit's first team last season, making 17 league appearances in a successful domestic campaign and also featured in eight Champions League matches.

Atsu also made his senior international debut for Ghana in June last year against Lesotho in a World Cup qualifier and has been a regular for the Black Stars ever since. He was also part of the squad that played the Africa Cup of Nations at the beginning of the year.
