Alfreton Town manager Nicky Law says Nottingham Forest may end up regretting allowing Danny Meadows to leave the City Ground and sign for Town.
The 19-year-old midfielder, who scored one goal in four games while on loan with Alfreton at the end of last season, has signed a two-year contract at the Impact Arena.
Law said: "I just think that every now and again, clubs get it wrong.
"He's a young lad with a lot of ability and a great attitude and outlook."
Law added: "If things go to plan, we can see some mileage in him. Primarily, he will be a very good player for us but Dan will also have a chance of moving on from us if he does the business."
