I want to know the answer to the following question:
Besides Arda Turan, what other player became eligible to play in 2016?
All the background I'm provided with is that "On 10 February, qualifying for the sixth Copa del Rey final in the last eight seasons, Luis Enrique’s Barcelona broke the club's record of 28 consecutive games unbeaten in all competitions set by Guardiola’s team in the 2010–11 season, with a 1–1 draw with Valencia in the second leg of the 2015–16 Copa del Rey.". Is that enough to answer the question?
Answer: no
