Brendan Rodgers praised a “comprehensive” performance from Celtic as they eased past Rangers with a 4-0 Scottish Cup semi-final win on Sunday.
Tom Rogic and Callum McGregor scored in the first half to put Celtic in control against their Old Firm rivals.
Ross McCrorie was then sent off shortly after half-time and Moussa Dembele scored the resulting penalty before Olivier Ntcham wrapped up the win with another spot-kick.
“We thoroughly deserved it,” Celtic boss Rodgers told Sky Sports. “In the first half we played well, scored two very good goals and had good composure. We were good defensively and were a threat going forward.
“In the second half we got the penalty and McCrorie got send off, and I still felt at times we could have been cleaner in our passing and could have one or two more goals with a final pass, but you can’t ask anymore, coming into a game here with so much on it, to come out winning 4-0 and playing so well, it was a great result for us.”

Victory moves Celtic a step closer to a historic double-treble and stretches their unbeaten run to 10 matches against Rangers.
They now look ahead to a meeting with Motherwell in the final on May 19.
“As a coach and manager you are always looking for that difference before the game, the one per cent, but I said to the players that the edge is them,” added Rodgers. “They are guys who shown all the supporters that they can achieve things and when big games come they turn up.
“It’s a huge credit to them and the focus this week has been very good, it was comprehensive.
“We know when we come back here it will be a tough game, Stevie [Stephen Robinson] has done a great job with Motherwell. We can really enjoy this last period of the season, today was a very good performance and a good win.”
