  3. Weah enjoys 'good vibe' at Celtic

    FT: Celtic 3-0 Airdrieonians

    On-loan PSG striker Timothy Weah tells BBC Scotland "it's really a dream come true" after scoring his debut goal for Celtic.

    Now the on-loan PSG teenager wants to "get to work and get busy" and score a few more.

    "It's a really good vibe," adds the United States international. "The boys have made me feel really at home and it's been easy to settle in.

    "I didn't know what to expect. I just wanted to go out there and play with a clear head."

  4. Should have been more - Rodgers

    FT: Celtic 3-0 Airdrieonians

    Celtic manager Brendan Rodgers is delighted with his side's start to the defence of the Scottish Cup after returning from their winter break.

    "It took us a bit of time to get going, but after that first 15-20 minutes, we started to find the gaps," he tells BBC Scotland.

    "Scored three goals, missed a penalty, had a lot more chances and had a goal ruled out that would have given Scott a hat-trick."

  5. Day of cup thrills

    It's been a long day in the Scottish Cup and it seems like a lifetime since Auchinleck Talbot became the first junior side to have reached the fifth round after their 1-0 win over Championship side Ayr United.

    That remains the result of the day, but it is closely followed by Stenhousemuir, sitting bottom of League One, forcing a replay away to Aberdeen from the Premiership.

    Dundee, bottom of the top flight, also face a replay away to Queen of the South.

    Championship leaders Ross County won away to top-flight Motherwell, while League One sides East Fife and Raith Rovers beat second-tier teams.

    Meanwhile, St Mirren came from behind with 10 men to ease the pressure on the side battling against relegation in the top flight by beating Alloa Athletic.

    Quote Message: Timothy Weah looks quick and strong. He can be a real asset for Celtic. I'm not sure Oliver Burke is an out-and-out striker, but his movement was better in the second half and he'll be happy to get 90 minutes under his belt
  7. 'Both teams can be happy'

    FT: Celtic 3-0 Airdrieonians

    Jim Duffy

    BBC Sportsound summariser

    Quote Message: Celtic are miles ahead of Airdrie in every department. But they kept at it and they had that one chance. If they had got that right on half time, you never know, but Celtic had more gears to go through

    Quote Message: It was damage limitation in the end, but Airdrie stuck to their tasks. They can be proud of their performance. They held their own for the majority of the game. In the end, Celtic were comfortable victors
  10. FULL-TIME Celtic 3-0 Airdrieonians

    Holders Celtic ease into the fifth round of the Scottish Cup with a convincing win over a battling Airdrieonians.

    It might have been different had home goalkeeper Scott Bain not made a triple save to deny the visitors an equaliser on the stroke of half-time.

    But two Scott Sinclair goals and a third from Timothy Weah give Brendan Rodgers' side a comfortable passage.

    Indeed, Celtic could have won by more against their League One opponents had it not been for several fine saves from David Hutton.
