Given John Guidetti's form for Celtic, you could have been forgiven for thinking that the striker was operating at the very top of his game.
Guidetti has been a revelation at Parkhead since arriving from Manchester City on loan in the summer.
The 22-year-old has scored nine goals in his first 10 games for the Scottish champions and has quickly established himself as a fans' favourite at Celtic Park.
However, his national team manager Erik Hamren believes that there is still more to come from Guidetti and says that he is playing below his potential.
"He will get there eventually but he needs to show more to get back to the level he was at before his injuries," Hamren is quoted as saying by the Daily Herald.
If there is indeed more to come from Guidetti, then Celtic fans will be rightly excited by what they may see in the future.
The Swedish international has already looked a class above anybody in their current squad and looks one of the finest players to wear the shirt in some time.
The Bhoys are hoping to do a deal to sign the hot prospect on a permanent transfer, but his good form has alerted the attentions of other clubs across Europe.
French giants Marseille are also reportedly keen on acquiring Guidetti's services and, if he can still play better, as Hamren predicts, then interest is only set to rise.
For now Guidetti will simply be concentrating on the matters on-the-field, though.
Celtic's form has been much improved in recent weeks and Ronny Deila seems to have imposed his methods successfully on the team.
They have now risen to the top of the Scottish Premiership and will be looking to extend the gap between them and the rest of the league when they take on third-placed Dundee this weekend.
