It looks to be a two-horse race for the crown at this stage, but Aberdeen's ex-Celtic midfielder Willo Flood took time out from his season to praise his former employers.
The 29-year-old played just nine times for Celtic during a year-long stay in Glasgow, but is well qualified to talk about two of Ronny Deila's new signings.
On deadline day, Celtic managed to tie up the signings of Dundee United duo Gary Mackay-Steven and Stuart Armstrong, and the pair got off to great starts having scored against Partick Thistle on Wednesday night.
The pair are considered to be two of the finest up-and-coming Scottish players around, and are expected to make big contributions as Celtic chase silverware in four competitions this season.
Flood played with both players at Dundee United, and told the Daily Record that both Armstrong and Mackay-Steven are 'top players' having seen the duo at close quarters.
"Peter [Houston, then manager] was talking to me about Stuart on that first day," said Flood, talking about when he arrived at Tannadice back in 2011. "Within a week I could see he was going to be a top player. He just needed to develop the other side of his game where he didn’t have the ball. Stuart has done that over the last few months and he’ll go on to have a great career."
"I remember Gary being in training with us for a few weeks and Peter was struggling to get the money to offer him a contract. But I’m sure [Dundee United chairman] Stephen Thompson’s glad now that he did give him the cash. Peter said he was going to sign a boy from Airdrie and believed he could develop him. Thankfully for the club and Gary, he developed into a top player," he added
Flood is currently rehabilitating from a hamstring injury, and will hopeful of facing his former club Celtic when they meet Aberdeen next month.
