Celtic manager Ronny Deila has told The Glasgow Evening Times that striker Nadir Ciftci needs to prove his worth with the Bhoys.
Ciftci, 24, smashed 33 goals in two seasons for Dundee United, and earned his big move to Celtic over the summer, with Deila bringing him in as a replacement for former loan star John Guidetti.
The Turkish forward arrived with high expectations, but has so far been a major disappointment for Celtic having barely featured in the first team.
With just one Scottish Premiership start and six substitute appearances, Ciftci hasn't had much of a chance to show what he can do, and he has even been demoted to the Celtic Under-21 side in a bid to get him up to speed.
Ciftci did score for the development squad against St. Johnstone on Monday, and he will now be hoping that he can seriously compete with Leigh Griffiths and Carlton Cole for a place in Celtic's starting line-up.
Having been the main man at Dundee United, this must be a strange situation for Ciftci, to be on the fringes of the Celtic side, and manager Deila has explained the striker's situation.
Speaking to the Glasgow Evening Times, Deila explained that Ciftci needs to adjust to life at a big club in terms of the competition for places, and urged the forward to 'speak with his feet'.
"Nadir’s situation is this; it is how it is at big clubs," said Deila. "There is always going to be competition. You have to show every day in training and in every match whether you start or get on that you are ready – like Scott Allan did at the weekend."
"Nadir has to speak with his feet and the same can be said about every player. We speak all the time. He knows we want him to work hard and he must always look to improve. We know he has the talent," he added.
