The Bantams bridged the four-tier gap between themselves and Aston Villa with a 4-3 aggregate win this evening.
If they can pull off another shock and defeat either Swansea or Chelsea in the final they will guarantee a place in Europe and Lawn has a light-hearted view on the possibility.
He said: "If we get into Europe I'll have to start learning some languages.
"I don't care who we get in the final, they will probably both batter us. Chelsea will have to declare at half-time if we play them!"
Lawn and Bradford will find out their opponents when Swansea welcome Chelsea to the Liberty Stadium tomorrow having earned a two-goal lead from the first leg at Stamford Bridge.
The final will be played on Sunday, February 24.
