The French giants are chasing back-up to Vedran Runje after losing Carrasso for the bulk of the season to a serious knee injury.
Manchester United outcast Fabien Barthez's chances of a return to Stade Velodrome are becoming increasingly remote while Troyes' Tony Heurtebis and Le Havre shot-stopper Carlos Kameni are deemed too expensive.
That has forced l'OM coach Alain Perrin to seek elsewhere for goalkeeping cover and he is dispatching scouts to watch three Euro 2004 qualifiers this weekend.
One target is Djurgardens keeper Isaksson with l'OM to run the rule over the 22-year-old in Sweden's Euro 2004 qualifier against Latvia.
Isaksson has usurped Magnus Hedman as his country's first choice keeper and Perrin could perceive him as the ideal candidate to challenge Runje on the South Coast.
Other options for Perrin are Stephane Cassard, with Troyes prepared to loan out the keeper, and veteran custodian Eric Durand who was released by Rennes at the end of last season.
