Steele moved to Panathinaikos upon Barnsley's relegation to League One in 2014 and is a regular for the Greek side.
The 31-year-old was rewarded with an improved three-year contract last summer and his form has reportedly alerted Three Lions head coach Roy Hodgson.
Hodgson's goalkeeping pool has been depleted by Jack Butland's recent injury and he is said to have asked his PAO counterpart Andrea Stramaccioni - an old friend from his Inter Milan days - to be kept up to date on Steele's progress.
"It's good I'm on the radar," Steele told the Mail. "It's a good enough sign at the moment.
"I'd swim across the ocean to get to France. I risked a lot coming here. Without sounding too confident I knew I could play at this level, that European standard."
Steele moved to Old Trafford from Peterborough United as a teenager, but never made a first-team appearance for the Red Devils.
Steele has kept 14 clean sheets in 27 Super League matches this season, but despite this Panathinaikos are only third in the standings - 28 points behind their runaway rivals Olympiakos.
