Leicester have signed Argentina international midfielder Esteban Cambiasso on a one-year contract.
Aston Villa boss Paul Lambert insists that there will be no release clauses in any new deal for star striker Christian Benteke.
Villa look set to open talks with the Belgian, if and when they secure their Premier League status - after a brilliant debut campaign in England.
Nominated for the Young Player of the Year award, Benteke has scored 18 league goals and is reportedly emerging as a target for a host of clubs.
Villa remain confident of keeping Benteke and will offer him new terms, but Lambert rubbished suggestions that a Demba Ba-style clause could be inserted.
"I don't think you can put any figures in because it just creates problems," Lambert told the Birmingham Mail.
"It's not something I've ever thought about with him. To be fair to Christian, he's never ever said anything about contracts or anything."
Lambert is hopeful of offering terms to a number of his squad and not just Benteke, with Andi Weimann, Matt Lowton and Ashley Westwood also in line for fresh deals.
"There's a few of the lads that you would think 'yes, he's done great' but there's no point in doing that yet," said Lambert.
"We've got to get over the line, that's the thing. We've still got goals to achieve. But it's something at the end of the season that you would look at.
"I think there's a few of them playing really well and Matty's definitely one of them. There's a few lads who you think have done really well but we've got to achieve something first."
