The Bhoys were active in January, snapping up defender Erik Sviatchenko, winger Patrick Roberts and striker Colin Kazim-Richards, before landing Norwegian wonderkid Kristoffer Ajer on a pre-contract deal ahead of the summer transfer window.
However, recent reports claimed that Celtic were already lining up targets for the summer, as The Scottish Sun suggested that Bhoys scouts had been to Denmark in order to watch Copenhagen midfielder Thomas Delaney in action, just weeks after signing his Danish international team-mate Sviatchenko.
Delaney, 24, has been with Copenhagen since he was a child, and has moved up through the club's ranks to eventually become a key player with the Danish giants.
The heartbeat of Stale Solbakken's midfield, Delaney has earned plenty of praise for his performances, but The Scottish Herald confirm that Bhoys manager Deila dismissed the possibility of signing Delaney this summer.
Delaney's future still appears to lie away from Copenhagen though, as his contract expires in just over a year, and Danish newspaper BT carry quotes from the midfielder admitting that he won't sign a new deal despite being offered a huge new contract.
That may yet spark Deila's interest, but for now it seems that Delaney won't be signing for Celtic - unless Deila's stance is a smokescreen ahead of a summer move for the midfielder.
Should Celtic move for Delaney this summer?
