Every summer, Celtic fans are worried that one or more of the club's key players could leave. This time around, the likes of Daizen Maeda, Reo Hatate, Cameron Carter-Vickers, Nicolas Kuhn and Arne Engels have all been linked with moves away. But considering how things have turned out for some of their high-profile departees, they should carefully consider any potential exit.
Last summer, the big-money move away from Celtic was that of Matt O'Riley. The Danish international joined Brighton & Hove Albion for a transfer fee believed to be in the region of €29 million.
O'Riley dealt with an injury early on in the season though and as a result, things did not get off to a good start. It was only towards the end of the campaign that he found his feet at Brighton and was starting games on a consistent basis.
Now, he is already being linked with a move away. And as reported by Lyall Thomas, Brighton have received a €30 million offer from Napoli for O’Riley. The Danish international is still considered important to the Seagull's project but the club will entertain offers that meet their valuation.
Napoli submit €30m bid for Celtic hero out of nowhere
Napoli are the Serie A champions, and in Antonio Conte, they have a manager capable of getting the best out of players. Just look at how he has transformed the game of Scott McTominay, who has gone from a heavily-criticised midfielder at Manchester United to the best player in Italy within the space of a season.
So, it is not hard to see why a move to Napoli might attract O'Riley. Now, it remains to be seen what kind of a transfer fee Brighton want to part ways with a player they signed just last summer.
As for Celtic, a O'Riley transfer could be important as well. That is because the club are believed to hold a sell-on clause.
