In October 2011, Ayina began training with US Quevilly, but only could be registered in January of the following year. On 20 March 2012, he scored twice against Olympique de Marseille, taking the club to the semifinals of Coupe de France.
On 9 July 2012, Ayina signed a contract with Spanish second division club Córdoba CF. On 21 August, he made his division debut, coming off the bench to replace Fuentes in the dying minutes of a 0–0 away draw against Real Murcia.
On 4 January 2013 Ayina was loaned to Écija Balompié in the third division, until June. On 2 September he rescinded his link with the Andalusians, and moved to Racing de Santander in the same division.
Ayina appeared in 17 matches during the campaign (only six starts, however) as the Cantabrians returned to the second level at first attempt. On 28 August 2014 he signed for Getafe CF, being assigned to the reserves also in the third division.
On 6 November 2015, after being sparingly used by his previous club, Ayina signed for League One club Rochdale. He was released on 8 January of the following year, after only one appearance in the Football League Trophy.
On 21 January 2016, Ayina signed for League Two club Newport County. He made his Newport debut as a second-half substitute versus Dagenham & Redbridge on 23 January 2016, scoring the first goal in the 2-2 draw. He was offered a new contract by Newport at the end of the 2015-16 season but the offer was withdrawn and he was released after he failed to accept the contract by the deadline of 10 June 2016.
