Delph is expected to be fit for Monday's derby with West Bromwich Albion.
El Ahmadi told the Birmingham Mail: "I'm not the manager and I don't know how it works with the English squad but he has the quality.
"Here in England he is a big player and a big talent.
"He is still young and was unlucky with injuries before and if he didn't have them then maybe he'd already be with the England squad. He has a great future in front of him.
"He's one of the best players in the team."
