"Atletico will continue to grow in the next few years, whether or not I remain at the club," said Oblak himself.
"What will happen, well nobody knows, not even me.
"I prefer to finish the season well and hopefully with a title. Then we'll see but I have a contract. I do not think of anything other than Atletico."
