The Rugby Paper is reporting that Harlequins are the current favourites to sign Bath prop Nick Auterac when his contract expires at the end of the season.
London-born Auterac, who moved to the West Country from Saracens three years, is keen to return to the capital next summer.
The 24-year-old is yet to agree a new deal with Bath and Quins want to swoop in to bolster their front row options.
Saracens are also rumoured to be interested in bringing the loosehead back to Allianz Park.
