Ronny Deila shares the two main reasons for Celtic failure, makes player revelation

By Coral Barry

Ronny Deila believes he struggled at Celtic because English was not his first language and was he was unfamiliar with the player pool in England and Scotland.

Celtic announced this week that Deila will leave his post as manager after just two years following growing frustration at performances and results among the supporters and the club hierarchy.

Deila has failed to light up the Scottish football scene as chief executive Peter Lawwell was hoping he would do when he took a chance on him in 2014.

The Norwegian has found life in Scotland challenging as he has tried to juggle learning English with educating himself on all the players inside England and Scotland, and he has admitted those two problems made doing his job as a manager almost impossible.

“It’s a very different culture in Scotland, a different way of thinking about football,” said Deila speaking to the Daily Mail. “It’s also a new market of players. You don’t know all the agents. In Scandinavia, we know all the players, so we have full control.

“But in Scotland or England, you don’t know the environment that well and it’s new. It’s also a new language.

“When you are in Norway, you can get a stone to jump when you are talking. But when you have to look for words, then it’s difficult. So it’s a lot of things when you are a foreign manager coming in.

“The managers who succeed in England are Portuguese, French. Why? Because they bring Spanish, Portuguese or French players. And they are the best players.

“You can’t bring Scandinavians because 99 per cent of them are not good enough. Dick Advocaat came here and had the whole Dutch team at Rangers. It’s easier, you know?”

Deila will leave the club on a semi-high as Celtic close in on a fifth consecutive Scottish Premiership title, but the Scottish Cup semi-final penalty shoot-out defeat to arch rivals Rangers last weekend was regarded by many as the final straw.

Celtic have struggled this season to tie up the Rangers-less Scottish league as quickly as they normally would and accusations have been thrown at Deila that his players are unfit and unwilling to follow his orders.

It has led to a complete breakdown between Deila and the supporters, and the team’s struggles in Europe against stronger opposition have also helped to seal his fate.

Celtic have just five league games left to play this season and they begin Deila’s farewell with a home tie against Ross County on Sunday afternoon.
