Roberts - Keane's in for a tough start
Clyde manager Graham Roberts has assured Roy Keane he will be given a full-blooded welcome to Scottish football at Broadwood on January 8.
The 34-year-old is set to make his Celtic debut in the Tennent's Scottish Cup third-round tie after the Scottish Premier League revealed he would not be eligible to play at Hearts on New Year's Day.
But the Bully Wee boss insists the arrival of Keane in Scotland will be a huge boost for the game north of the border.
Roberts told Sky Sports News: 'Roy Keane is a world-class signing but he will know he has been in a game against us.
'It will be a full house and we are looking forward to it. But it is a big signing for Scottish football. The quality of the player is absolutely unbelievable.
'This is a big coup for Celtic and we are delighted he will be making his debut against us.'
Keane is set for his first Old Firm derby on February 12 when the Hoops travel across Glasgow to Ibrox.
But the former Rangers defender believes the Irishman will receive a warm welcome from Light Blues fans.
Roberts added: 'I like to think he will get a good reception from the Rangers fans. They will be looking forward to that but it has made Celtic stronger in midfield.'
