The two young midfielders have gone in slightly different directions since breaking through into senior football full-time.
Whilst both have plied their trade away from Chelsea on numerous occasions, only one has cemented a regular slot for the Champions League holders.
Mount went away to Vitesse Arnhem and Derby County before becoming arguably the Blues’ most consistent performer of the past two years.
In the same period, Gallagher has enjoyed decent spells with Charlton Athletic, Swansea City and West Bromwich Albion.
His latest stint is currently at Crystal Palace, who he scored twice for last weekend away to West Ham United.
For the 21-year-old, the ultimate ambition will be to represent Chelsea on a permanent basis, a dream that Mount is now living.
“If I copy that pathway I’ll be buzzing,” said Gallagher, about his fellow Englishmen’s footballing journey.
Have a strong campaign with Palace, then there is every chance Gallagher will return to Chelsea immediately and indefinitely.
Thomas Tuchel already had a good look at the Cobham prodigy during pre-season, so is aware of his abilities.
It might be necessary for the German coach to recall Gallagher next June, depending on how his transfer strategy works out.
Chelsea are still seemingly on the search for extra central midfield cover, something they are unlikely to land in this window.
They might return to this in January, or wait until the season’s completion and recover Gallagher services to add extra depth in that position
