Asked whether spirit among players would keep the squad together, Vardy replied: 'I think we are hoping it will.
'There will be names thrown into the hat all summer but the group of lads we have, winning the league, and having Champions League football next season, you hope it keeps everyone together.'
He added: 'Nothing has really been spoken about like that between the lads. We're just concentrating on each and every game as they come.
'One thing we want to do is keep that mentality of winning. We will be back on that training field this week and hopefully putting a performance in on Sunday that gets us another win.'
Looking further ahead, Vardy said Leicester's counter-attacking approach and high-energy tempo might be successful in Europe's elite competition.
'We are definitely hoping so. We have got ourselves into this situation playing that way, why change it?' he said. 'It has worked for us so we will hopefully make sure it works for us again.
'I'm not sure we will surprise people. Leicester has been on everyone's radar all season, they will have heard all the stories coming out about how well we are doing. A lot of the European teams will have probably been watching us.
'They will have to do their homework as well as we'll have to do our homework on them. Once it comes to game time it will be 100 per cent going out and hopefully getting wins.'
