Celtic missed out on signing Atalanta defender Timothy Castagne despite making an offer of £8.7 million in January, according to Sky Sports journalist Gianluca Di Marzio.
The Bhoys wanted to sign the 23-year-old Belgian right-back to boost their defensive options but reportedly missed out.
The position has been a problem for Celtic this season, with Mikael Lustig and Anthony Ralston the men manager Brendan Rodgers has been relying on.
Prior to the end of the transfer window, he brought in Jeremy Toljan on loan from Borussia Dortmund, and he has immediately slotted into the defence.
However, it seems that the Germany Under-21 international may not have been Celtic’s first choice.
Castagne has made 20 appearances in all competitions for Atalanta this season and made his international debut for Belgium last September.
Since making the move from Genk in July 2017, he has become a key part of the Italian side’s defence.
Rodgers was keen to bring in defenders during the January transfer window and may have had a number of targets lined up.
Although he missed out on signing Castagne, he brought in Andrew Gutman and Manny Perez to give himself more options.
Calvin Miller also returned from his loan spell with Ayr United to ease the club’s shortage of defenders.
However, in recent weeks, they have welcomed back Dedryck Boyata, Kieran Tierney and Lustig from injuries.
The Bhoys are six points clear at the top of the Scottish Premiership and after 5-0 win over St Johnstone in the SFA Cup at the weekend, are back in action against Valencia in the Europa league on Thursday.
