The 22-year-old midfielder has been a regular in the Championship outfit’s first team over the past three campaigns and has been capped by England at Under-18, 19 and 20 levels.
Osborn’s form resulted in the club tying him down to a new four-year contract in the summer and he has gone on to enjoy a solid start to this season with one goal and five assists in 20 appearances.
Premier League rivals Watford have reportedly been keeping tabs on Osborn and could be set to make a £3million bid to try and secure his signature in the January transfer window.
However reports are now rife that Swansea have also joined the race and could also make a move as Bob Bradley looks to bolster his midfield in January.
Falkirk attacker Louis Longridge is more than familiar with the underdog tag the Bairns will take to Ibrox on Sunday.
