Ronny Deila is under serious pressure as Celtic manager.
Charlie Nicholas has told Sky Sports that Ronny Deila has not been strong enough in the transfer window at Celtic.
Deila has generally shopped on a budget during his time at Parkhead, with most his acquisitions being bargain buys.
When Deila has spent, he generally has invested in defenders, and Nicholas has questioned the logic behind the Norwegian’s approach to buying players.
"I don't think he has been strong enough to stand up against it and say 'I don't want the players you are giving me, I want better players than that’,” Nicholas said. “They spent £6m on two centre-backs. Why not spend £6m on a couple of exciting, attack-minded players?
"But they go to Dundee United, they buy someone for £750,000 or £1m. They have gone down the cheap and cheerful route - and now it is not cheerful anymore.”
Celtic have suffered with a lack of forward options this season, with Leigh Griffiths their only striker to have scored on a regular basis.
Although Deila did try to solve this problem in January by recruiting Carlton Cole - the former West Ham United man has failed to make much of an impression.
Deila is now under serious pressure at Celtic, even though they look on course to win the Scottish Premiership title.
The Bhoys have not looked particularly convincing in any competition this season, and their latest defeat against Rangers in the Old-Firm derby has increased the frustrations around Parkhead even further.
Celtic's next match comes against Ross County at the weekend.
