Celtic manager Ronny Deila has commented in the Daily Mail suggesting the problems, which face any new player joining his club.
Deila cited several challenges new players face, when he was quizzed over the starts Stuart Armstrong and Gary Mackay-Steven had made at Parkhead.
“Just coming to Celtic - dealing with the contract, the media and so on - used a lot of mental energy in Gary and Stuart,” said Deila.
“Then the training is at a much higher tempo then they have been used to before. The total loading gets too much.”
Armstrong and GMS have both settled in well following moves from Dundee United and Deila may already have one eye on the additions he’d like to make this summer.
Celtic still have a great chance of domestic success, but the Norwegian may want to beef up his squad again so the Bhoys compete that little bit harder in a European setting next season.
The manager is vital for any new player joining the club, if they feel they are struggling to adapt and settle down.
It’s encouraging that he’s demanding the very best from any new players joining the club from the second they set foot on the Celtic training pitch.
It allows the club to maintain their high standards and training will be particularly intense at the moment following a disappointing defeat against St Johnstone earlier this week.
Deila may well point to the examples of Armstrong and Mackay-Steven as sources for advice and if they can both perform over the rest of the season, they’ll be model examples of how to adapt and settle at the club.
