Former Rangers captain Barry Ferguson has refuted suggestions Celtic's summer transfer business has seen them stand still.

The Hoops spend over £15m to secure loan players Jota, Cameron Carter-Vickers and Daizen Maeda.

But they also splashed out on Argentine youngster Alexandro Bernabei in a £3.75m deal and signed Australian international Aaron Mooy to boost the midfield.

And Ferguson admits the league table proved Celtic were the best team in Scotland last year, citing them as "dangerous" opponents for his old club.

Asked if Celtic have stood still, he told the Daily Record: "Celtic have kept last season’s squad together but has the starting line-up improved? Good question.

"I wouldn’t say they’ve stood still because the quality is still there and they were the best team in the country last season. 

"The league table doesn’t lie. Ange Postecoglou has tweaked their style of play this summer and the Aussie has said the team will always evolve while he’s in charge. 

"They might not have added any stand-out signings but are still very dangerous."
