Celtic captain Callum McGregor says the club's need for fresh acquisitions remains apparent despite their Champions League exit on Tuesday evening.
Brendan Rodgers' men were beaten on penalties in Kazakhstan by Kairat Almaty.
Celtic will now compete in the Europa League this season, although skipper McGregor insists more squad depth is needed: "Everyone has been quite vocal about what we need," he said after last night's loss [BBC].

"We need help, we need the players, we need to have a strong squad if we want to compete on all fronts.
"That doesn't change after tonight - the players still need help, [we] need bodies in the door."
The transfer window in Scotland shuts next Monday.
Before then, Celtic are expected to complete deals to sign Marcelo Saracchi on loan from Boca Juniors and Michel-Ange Balikwisha from Royal Antwerp.
The latter completed his medical in London today ahead of a permanent move worth £5million, claims Sky Sports.
Asked last night whether the financial gulf between the Europa League and the Champions League will impact Celtic's transfer business between now and the close of the window, boss Rodgers simply stated: "I haven't a clue, I really don't know."
