Kuszczak has another year on his contract but Ferguson has made no attempt to assure him he is still wanted at Old Trafford.
The ex-West Bromwich Albion goalkeeper therefore accepts it is time to leave after five years at United and is now weighing up his options, with his former club in the frame.
"I haven't spoken with Alex Ferguson," he said.
"He has told me nothing. He never tells me anything. I don't know if I can stick it any more.
"I have some offers and we will see what happens with them.
"I think I will stay in England. I have been in the country for seven years and people here know what I can do."
