When asked how Boyata was feeling about the whole situation, Lichtenstein, speaking to Belgian newspaper DH.be, said: 'Dedryck is disappointed.
He said: "I haven't had dealings with Dedryck's agent, it has all been through the club".
'My concentration is really on the players that are going to play and are going to be fit to play and see if we can go out there and meet the challenge. The club have been in negotiation with Dedryck's agent from a year ago.
"The only other point; Dedryck's agent turned up (on Friday) at the training ground, which is closed the day before the game".
"We will see over the next couple of days".
"It's nice to have teams like Rangers interested in me - I think everyone knows I'm a Rangers supporter - but obviously it's up to the two clubs to work something out", Lafferty said. "Of course we want quality players but there's still improvement in this squad, this team, lots of young players so we'll continue to work with and improve them", he said. "All I'm focusing on is working hard in training and every weekend put a performance in and we'll see where it takes me".
"The official offers were left unanswered, sending the message clearly that Celtic did not want to sell the player". His upturn in form earned him a World Cup call up for Belgium and he played against England in a group stage fixture in the absence of Vincent Kompany.
Hearts' win moved them to the top of the Scottish Premiership - temporarily at least - having also won their first game of the season away at Hamilton. We have to be able to cope with that.
Hearts manager Craig Levein admits that he smelled blood when he saw five changes had been made to Celtic's side amid two pivotal Champions League qualifying games.
"I'd read somewhere else about walking away". Other things around me - I can't concentrate on that.
