Former Celtic striker Andy Walker has claimed that the club is not progressing under manager Ronny Deila.
The Hoops were beaten in the Champions League playoffs last night as a 2-0 defeat to Malmo saw them exit the competition 4-3 on aggregate.
Deila won the Scottish Premiership and the Scottish League Cup during his first season in charge at Celtic Park, but Walker has questioned whether the Norwegian is the right man for the job.
"There's too much talk of progress at Celtic under Ronny Deila. Any manager in Scottish football and the Premiership could come up with the results Deila has over the last 14 months," he told Sky Sports News.
"With that budget, the players they have and all the facilities, everyone in the Premiership could deliver the title and odd cup. Deila has fallen short here."
Deila admitted after last night's defeat to Malmo that his side looked "scared" during the match.
