The agent of former Real Madrid captain Iker Casillas says he wasn't short of offers this summer.

Casillas kept a cleansheet on debut for Porto over the weekend.

Santos Márquez told AS: "The idea of joining a team which had qualified for this year's Champions League was appealing.

"We did study a few offers from the Premier League but none of them really interested Iker too much. Then Porto appeared. He wanted somewhere near, a good city and Porto fitted the bill. The economic issues were resolved in two trips. They didn't believe that Iker would opt for Porto while he had other options."
