Press reports claim the former Benetton, Cheetahs and Italy coach is understood to be nearing a deal with the Scotstoun side. However, it's understood negotiations have gone on longer than expected as Smith is in contract with the Italian Rugby Federation and compensation will be due.
Smith has been the Italian federation's director of high performance since being replaced as Italy coach by Kieran Crowley last year.
The club have been linked with a host of big names, including Dean Richards and Todd Blackadder, since parting ways with Danny Wilson in June.
