On 21 September 2013, he scored his first goal for Villa, seconds after replacing Christian Benteke, against Norwich City which proved to be the winning goal in a 1–0 victory. On 9 November 2013, he scored his second Villa goal with a header in a 2–0 victory against Cardiff City. On 4 December 2013, he scored the second goal in a 3–2 victory over Southampton. On 21 December 2013, he scored the only goal for Villa in a 2–1 loss to Stoke City at the Britannia Stadium.
