Vitesse's Buttner open to other options as Southampton move hits difficulties
The 23-year old was set to make the move to St Mary's Stadium but some previously unseen issues caused the deal to fall through and now he is back to square one.
"I can't do anything other than wait," Buttner said in Voetbal International.
"I had a good feeling with Southampton, but the transfer depends on several factors.
"At the moment all options are open again."
