Celtic new boy John Guidetti reckons training with some of the best players in the world at Manchester City has helped make him a better striker.
The Swedish forward joined City in 2008 and, despite not making a competitive first-team appearance, he relished his time at the Etihad.
"It's not easy to play in Manchester City as a young player, it's a very competitive team," Guidetti said.
"But I've been training with some of the world's best players, I feel good."
The 22-year-old's season-long loan deal with the Scottish champions was rubber-stamped last week by Fifa, despite some of the paperwork being filed after the transfer deadline had passed.
And while other clubs had moved for the hitman, he says his heart was set on a switch to Celtic.
"It's a massive football club, known in the whole world for their amazing history and amazing fans," he added.
"The club is very well known in Sweden for the people that have played here before and the things they have done here. When Celtic come you don't say no, at least not me."
Guidetti says he is is ready to be pitched into the action on Saturday against Aberdeen, but admits it may take him time to hit top form.
"I can't promise anything because you never know in football, but all the fans can expect is that I'm going to give 110% every game and work my socks off," he said.
"If the manager wants me to play one minute I play one minute hard, and if he wants me to play 120 minutes and take a penalty that is what I will do.
"I would love to hit the ground running but anything can happen in football and if I don't hit the ground running it's not like I'm going to stop - I'm going to do my best in every game."
With fellow Swedish striker Henrik Larsson having made himself a club legend during his time at Celtic, Guidetti was keen to play down any potential comparison.
"It's very harsh to compare to someone like Henrik Larsson because what he did here was not normal, it was truly amazing," he said. "If I can do a small toe-nail of what he did it would be amazing."
Celtic manager Ronny Deila is delighted to have captured Guidetti and Serbian striker Stefan Scepovic, and he also revealed skipper Scott Brown could return to action against Aberdeen after an injury lay-off.
"I think we have got some good signings and I'm very happy. We got what we wanted and that's fantastic," Deila said.
"Scepovic is a box player. John Guidetti is also a goalscorer, a real number nine.
"Scott Brown is like a new signing. He is training well and could go into the game on Saturday. Everybody knows how important Scott is for Celtic, he's a leader and he shows the way - a huge player to get back on the pitch.
"Aberdeen is the biggest club besides Celtic, I think. They have a good team and they beat Celtic twice last year so it's going to be an exciting game."
Deila also revealed defender Virgil van Dijk is "very happy" at the club, after the Dutchman was reportedly angry at not being sold during the recent transfer window.
