New assistant manager John Collins has insisted that the club will only listen to ‘crazy bids’ for defender Virgil van Dijk.
The Dutch defender has been linked with a string of clubs down south after his debut season at Parkhead, with the likes of Southampton and Newcastle circling.
However, Collins has stated that club have little desire to sell the 22-year-old who has impressed since his move from Holland last summer.
Collins said: “When you have good players there is always going to be speculation and teams interested in them, so no problem with that at all.
“We would love to keep all the top players but everyone knows if crazy bids come in you never know. But at this moment in time we need them all playing for Celtic.”
