Celtic chief executive Peter Lawwell has told the club's official website that he took a risk when appointing Ronny Deila as manager last summer.
Deila, 39, forged a great reputation for himself in Norway, winning one cup and one league title as manager of Stromsgodset before his surprise move to the Bhoys.
Former boss Neil Lennon left the club last summer after great success in Glasgow, and Celtic sprung a surprise by handing the reins to Deila - but so far their faith has been repaid in a big way.
Deila has won the Scottish League Cup, and then secured the Premiership title on Saturday after Aberdeen's defeat to Dundee United, meaning Celtic have now won four league titles in a row.
The treble eluded Celtic after a Scottish Cup semi-final defeat to Inverness Caledonian Thistle, but a double is a strong start for Deila, who will now be looking to build on that next season.
Almost a year since his arrival, Lawwell has reflected on Deila's first season in charge at Celtic Park, and admits that whilst he took a risk when appointing a young, foreign manager, his faith has certainly been repaid, praising Deila for being 'fantastic'.
"When we knew that we were looking for a manager, we had a number of candidates. Ronny, we knew about," said Lawwell. "Clearly, as part of my job, you need to be aware of what’s going on in the football world and we knew about Ronny and what he had and what he achieved, and the skills and attributes he had, so when we were looking for a manager he was on the list.
"We met him, he was very, very impressive and although some would think we took a risk – which we probably did – we felt that he was ideal candidate for Celtic and he fitted really well with our strategy – which is to create a winning, entertaining football team, to create football players, to create a team, a backroom staff and develop players, and he’s been fantastic."
