Munster have not finalised any new deals with players for next season, but the club are interested in the services of James Hart and Chris Farrell.
Munster have already secured the services of Jaco Taute until the end of the current season after the South African was originally set to return to the Stormers earlier this month.
Certain French media have reported that Munster are interested in Hart and Farrell, who play in the Top 14 for Racing 92 and Grenoble respectively.
Erasmus has admitted that talks have taken place with the French-based pair, but that they are among a number of options drawn up by the two-time European champions.
“Until you have everything signed and sealed, it would be stupid to speculate,” he told RTÉ Sport.
“We are talking to even more guys who are Irish qualified who we want to get here, some we have succeeded with, some we have not. Those two [Farrell and Hart] are definitely on the radar, but there’s nothing yet to announce.”
