Sergio Ramos says the Champions League was "important" in his decision to return to boyhood club Sevilla this summer after his Paris St-Germain contract expired.
The centre-back, 37, is hoping to shake off a calf injury in time to face Arsenal at the Emirates on Wednesday
Ramos won Europe's top competition four times during 16 seasons at Real Madrid.
"Sevilla were playing in the Champions League and that was a plus in making such a decision," Ramos said.
"I had received offers of going abroad, to Saudi Arabia, for instance - but this was a debt I had to my club, to Sevilla, the first team where I triumphed.
