Chelsea signing Christian Atsu is aiming to prove he is good enough to play for the Premier League giants during his season-long loan spell at Vitesse Arnhem.
The 21-year-old Ghana midfielder was immediately sent out to the Dutch side after joining Chelsea from Porto.
Atsu said: "When Chelsea came in for me I saw a good opportunity to work with a massive club and great coach."
He added: "I know I have to prove myself at Vitesse first and I am determined to do just that."
