It has been a quiet summer at Celtic thus far but that is expected to change in the coming weeks as Brendan Rodgers gears up for a busy transfer period ahead of next season's Scottish Premiership title defence.
There have been no new arrivals thus far but Celtic are in the market for a new first-choice goalkeeper following the retirement of Joe Hart, who hung up the gloves on a glittering career at the age of 37 at the end of last season.
Celtic are also on the hunt for outfield players with defence, midfield and attack all likely to be with and last season's loanees, Benfica's Paulo Bernardo and Norwich's Adam Idah, understood to be among the key targets.
Rodgers will also have decisions to make over several members of his current squad, with further departures likely. Two first-team players have already left, the aforementioned Hart followed out the exit door last week by midfielder Sead Haksabanovic, who joined Swedish champions Malmo after spending last season on loan at Stoke City.
Here, we take a look at how the future might look for all 30 first-team players currently contracted to Celtic...
29. Mikey Johnston
The 24-year-old enjoyed a hugely successful loan spell at West Brom last season, scoring seven times in 18 appearances, and the Baggies are tipped to make a move to sign the Republic of Ireland winger permanently this summer. They will need to stump up though with reports claiming Celtic will be looking for around £5-6m for a player who still has two years left on his contract. Photo: Craig Foy - SNS Group
30. Marco Tilio
The Australian winger managed just two substitute appearances last season after joining on a five-year contract from Melbourne City before being farmed back to his previous club on loan. The safe bet would be on the 22-year-old returning Down Under - either permanently or on loan - as the move to Celtic has not worked out. Photo: Rob Casey - SNS Group
