Experienced midfield duo Simon Davies and Carl Fletcher are also ahead of Allen in Toshack's pecking order and Wales youth coach Brian Flynn has urged the Swans rookie to be patient while waiting for his Wales senior call.
Allen was an able deputy for Swansea midfielder Ferrie Bodde when the Dutchman was ruled out for the season with a cruciate knee ligament injury.
Allen has played 15 times for Roberto Martinez's Swans this season and played a starring role in their FA Cup run.
And he said: "Hopefully international recognition will come as the performances and the game time come as well.
"Hopefully it's something that I'll get a chance to do in the future."
Allen, who has played nine times for the Wales U21s, came back earlier than expected from a thigh injury to play in Swansea City's 2-2 draw against Derby County at Pride Park in the Championship on Tuesday.
