Ronny Deila feels Rangers are weakest team left in the League Cup
Celtic manager feels the Ibrox club's Championship status may count against them in the last four.
Celtic manager Ronny Deila believes Rangers are the weakest of the four teams left in the Scottish League Cup.
A hat-trick from John Guidetti helped the Hoops beat Partick Thistle 6-0 and seal a spot in the last four.
City rivals Rangers beat St Johnstone in their quarter-final along with Premiership pair Aberdeen and Dundee United.
Speaking about potential opponents, Deila said: "This is about winning the League Cup, I said I want to win the treble and we'll take whatever comes in front of us.
"It's a semi-final; whoever we are going to meet is going to be a biggy. So we're looking forward to it."
Rangers have beaten Premiership opposition in the form of Inverness CT and St Johnston on the way to Hampden.
When pressed on the quality of the Rangers squad, the Hoops boss admitted their Championship status may go against them
"That's also hard to say. I think the best teams are in the top division - that's how it is," he said.
"We'll see, the teams in the top division are playing at a higher level every week and that's an important thing.
"We play in Europe and you have the possibility to play against the best tempo."
Speaking after the win over Thistle, forward John Guidetti insisted Rangers or any other opponents will be "going down" if they are drawn to face the Hoops in the semi-final.
Celtic will learn their fate on Saturday but Deila remains confident no matter who they draw.
"The cup is the cup and you never know," he added.
"Whoever you meet is going to be exciting and it's going to be two good semi-finals.
"I understand everything about that, but again it's about winning.
"If we can beat two more teams we will have a trophy, and that's what we want."
