After a bizarre goal drought, it appears that Celtic striker John Guidetti is finally getting back to his best.
The Swedish international is on a season-long loan deal from Manchester City, and started his Celtic career in sensational form with ten goals in his first 11 games.
However, the 22-year-old then went on a run of ten games without a goal, losing his place in the starting line-up to Leigh Griffiths in the process.
Now though, he seems to be getting back to his best form. Guidetti came off the bench against Inter Milan on Thursday to rescue a 3-3 draw with a last-gasp equaliser, and then started against Hamilton Academical on Sunday, scoring the third goal in their 3-0 win.
With his Manchester City contract set to expire at the end of the season, Guidetti is available to sign for any club on a free transfer at the end of the season, with Celtic surely interested in making his stay a permanent one.
Yet according to The Scotsman, French giants Marseille are aiming to sign Guidetti this summer, and are prepared to pay him around £60,000-per-week.
Manager Deila was asked about Guidetti's future after watching his side beat Hamilton 4-0, and told The Scotsman that whilst he hasn't heard the rumours, he wants Guidetti to stay at Celtic Park long-term.
"I haven’t read that," admitted Deila. "There is a lot in the newspaper that is not true. I don’t know, it’s rumours. I think he should stay at Celtic. But I have said that many times."
"He has been in and out of the team here. Why? Because he hasn’t been good enough. When he plays at his best level he is good enough and then he will play. Then he will develop. He is still young and hopefully he will want to stay at Celtic," he added.
If Guidetti can replicate his early season form in the final weeks of the season, then Celtic may well be prepared to break the bank to keep him - but that recent goal drought will be a concern, and Deila will be hoping the two goals in the last two games aren't just a flash in the pan.
