'The boys stayed professional' - Kennedy
FT: Clyde 0-3 Celtic
Celtic assistant manager John Kennedy tells BBC Scotland: "Confidence taken from wins gives you the mindset you can go it again. It's been a great mentality from the team in the way they've approached every game.
"At the [quarter-final] stage it's always going to be difficult no matter who you get. It's a place we've done well of late [at St Johnstone], but delighted to get through first and foremost.
"We felt comfortable, it was a controlled game - the boys were professional. We'd have liked to have scored more goals but Clyde defended well and stayed in a good shape.
"Ntcham has been terrific - especially since the turn of the year before Christmas. He's really kicked on since the training camp in Dubai. He's showing with great desire and hunger, and it's difficult to leave him out of the team.
Joy for Bayo

'We competed well against the country's best' - Lennon
FT: Clyde 0-3 Celtic
Clyde manager Danny Lennon tells BBC Scotland: "The positives we'll take out of this game is that we competed for long periods against the country's best.
"The shape for the majority of the game was very good and the desire and hunger to get back behind the ball.
"The simplicity in the way Celtic plays is very good, and I thought they had a very good disciplined performance.
"We more than matched them in the second-half, but quality is always going to come through.
"The level of training has went up three or four notches this week - as a manager you're pleased with that but also frustrated. That's got to be the level we're always at."

Post update
FYI, Celtic's trip to St Johnstone will likely be on Sunday 1st March, because they play in the Europa League the Thursday before.
Rangers are also still in the Europa League of course, but their away leg against Braga in the last 32 is being played on the Wednesday.
Tasty ties
A tasty last eight draw there with Inverness CT the only non-Premiership side left. They face a tough trip to Easter Road but have good pedigree in the competition having won it in 2015 and reached the semi-final last year.
Hearts v Rangers at Tynecastle should be a cracker given Daniel Stendel's side emerged victorious in the last meeting at the same venue recently.

Quote Message: Celtic went about their business very professionally - I thought their attitude was terrific, none more so than captain Scott Brown, and they ultimately deserved to go through comfortably

'Bayo sends message to Lennon with goal'
FT: Clyde 0-3 Celtic
Jim Duffy
BBC Sportsound summariser
Quote Message: Bayo had a couple of chances to score - his movement was terrific, it looks simple, but he gets to the byline, checks him, and gets his technique right. He'll be delighted and is sending a message out to Neil Lennon that 'you may have signed a £3m striker in Patryk Klimala but I'm still here'

FULL-TIME- Clyde 0-3 Celtic
A straightforward win for Celtic who progress to the quarter-finals. That's 12 away wins in a row domestically.
Olivier Ntcham cracked in the opener with Scott Brown squeezing in the second from a yard out. The second half wasn't a great spectacle, but substitute striker Vakoun Bayo capped things off in the final minute.
Clyde were spirited, but ultimately never really threatened.
GOAL- Clyde 0-3 Celtic
Vakoun Bayo
And the Ivorian gets his goal!
He finishes well inside the post from close range after good work from Moritz Bauer, who set him up.

GREAT SAVE!
Clyde 0-2 Celtic
Superb goalkeeping by Clyde's David Mitchell as he claws away Boli Bolingoli's cross. Vakoun Bayo had a tap in there if he didn't get there.
Shortly after, Ryan Christie's effort cracks the top of the bar!
