Speaking to Sky Sports, former Celtic striker Charlie Nicholas has expressed his belief that the Bhoys will once again win the Scottish Premiership title, although he is not convinced by the side in Europe.
Nicholas said: “They'll win the league, there's no question about that, but this [Europe] is the true judgment for Celtic and unfortunately it's in these situations where they're weak.”
Ronny Deila’s men currently sit first place in the Scottish Premiership, six points ahead of closet rivals Hearts, with 10 wins from 13 games.
The Bhoys were always going to be favourites for the league title, and it is why they are judged for their performances in Europe. However, they have yet to show any sort of form in the Europa League, after losing in the Champions League qualifiers at the beginning of the campaign.
Celtic have lost two and drawn two of their four group games, and whilst they can still qualify for the next round of the competition, it will be an extremely hard task.
They look completely below par when taking to the field in Europe, and there is the worry that if the Bhoys start to show this form in domestic football, they could drop out of the race to win the league.
Considering the lack of quality amongst their league rivals, this should not be too much of a worry, but it is certainly not something which suggests a long term successful future for Celtic under Deila’s management.
