Rotherham United boss Steve Evans was delighted with the impact of on-loan Arsenal goalkeeper Emiliano Martinez.
Martinez concluded his loan on the weekend.
Evans stated, "I think he's been great for us. We're going to be watching Emi on Match of the Day in six to eight months and then for a number of years as Arsenal's number one.
"I know for a fact he has a couple of clubs in the top division in Spain wanting to take him on season-long loans. It wouldn't surprise me then that if we're not seeing him in the Premier League we'll be seeing him against Barcelona and Real Madrid. That's how well he's regarded."
