Don't forget that television coverage of the big game is starting shortly on BBC One Scotland.

Former Scotland internationals James McFadden, Charlie Mulgrew and Leanne Crichton join host Jonathan Sutherland, with Liam McLeod on the live commentary from Hampden.

Angus MacDonald, who is deputising for the suspended Graeme Shinnie as Aberdeen captain, tells BBC Scotland: "We've come with a gameplan and we're going to stick with it. It's a massive game for us - anything can happen in the cup.

"We've looked at that, we've looked at videos and done all our analysis and we're going to cause them the same problems that hopefully we've done in the past."MacDonald says the team haven't heard yet from Jimmy Thelin, who will take over as manager this summer, but that news of the appointment had been a pre-match boost.

"It's probably given the fans a lift more than anything - we've got to concentrate on the job we've got in hand," he adds.

Celtic captain Callum McGregor tells BBC Scotland: "Obviously I've missed the last few weeks, but you get to a cup semi-final, you see the pitch, you see the weather, it's the perfect day for football, so I'm delighted to be back in.

"It's great to get on the pitch today, get some minutes in and hopefully keep getting stronger.

"This club is built on big games and we've got another one today. It's important we do our job and get ourselves into the final.

"We know Aberdeen have a threat on counter attacks. They're a physical team, so we have to bring our A-game, we have to be good with the ball, good in transition and then try do the right things to get a good result."

We all knew Aberdeen captain Graeme Shinnie would miss out through suspension and his absence is the only change from last weekend's 0-0 draw with Dundee.

Dante Polvara comes into Peter Leven's midfield, while centre-half Angus MacDonald takes the armband in Shinnie's absence.

The headline Celtic news is that captain Callum McGregor starts after two substitute appearances since his return from injury.

Liam Scales is also fit to return to central defence.

It means Maik Nawrocki and Tomoki Iwata drop to the bench.
