Former England fly-half Olly Barkley looks likely to leave Grenoble because of a clash of rugby philosophies.
Director of rugby Fabrice Landreau says he and Barkley to not share the same "concept of rugby," and the former Bath star's days in France look numbered.
Barkley spent last season at Racing Metro before moving to Grenoble in the summer but the switch has not worked out.
Landreau told Rugbyrama: "It's a big failure to not having been able to properly integrate into our team project. He is a very professional guy, very polite, very gentlemanly.
"Unfortunately, we do not have the same concept of rugby. He is disappointed with our game. He wants a much more stereotypical game, much more organised. He wasn't able to find its place."
Franck Corrihons, Grenoble's backs coach, said: "It is a disappointment for us, but especially for him. Unfortunately, he never managed to blend in. He had several opportunities early in the Top 14 season and Amlin Cup, but he never managed to leave his mark."
Barkley is likely to return to England and is unlikely to be short of offers.
