Norwich City have warned Aston Villa they still must agree a compensation fee for Paul Lambert.
Norwich insist no deal has been finalised even though Lambert has been confirmed as Aston Villa manager.
The former Celtic star succeeds Alex McLeish, who was sacked following the final game of the season, to become the fourth manager at Villa Park in less than two years.
Villa have confirmed Lambert's appointment with a brief statement on their website: "The board of Aston Villa are delighted to confirm that Paul Lambert has been appointed Villa manager."
However, Norwich released a statement which revealed the deal has not been completed.
It read: "Following today's announcement by Aston Villa that they have appointed Paul Lambert as their new manager, we would once again like to place on record our sincere gratitude to Paul for everything he has done for the club.
"Everybody at Carrow Road wishes him all the best for the future.
"Some media reports are suggesting we have agreed compensation for Paul's services with Aston Villa, however this is not the case.
"We will continue to discuss this matter privately with Aston Villa."
