The Levante man has been linked with Arsenal, Everton and Liverpool following a string of impressive performances during the World Cup, and the ex-Wales international believes that he would be well suited to the English game.
"I think looking at the Premier League now he could do [well]," Southall told talkSPORT.
"I thought he did really well [at the World Cup]. The only thing I would question was his kicking because he booted it down the middle and gave away possession I don't know how many times last night.
"His shot stopping was good, his [claiming of] crosses were debatable, but I think he would get away with that in the Premier League, his bravery was good because he came out sliding at people's feet and his handling was decent. So yeah, I think he would do all right in the Premier League."
Costa Rica's impressive World Cup run was brought to an end by the Netherlands at the quarter-final stage, with the Dutch triumphing on penalties following a goalless draw.
