The Swedish striker laughed as he still referred to Kalmar as his team.
He arrived as the top goalscorer with Kalmar in the Swedish top-flight and was clearly happy at the club. However, the chance to test himself abroad proved too much of a lure and he made his way to Yorkshire.
But he clearly still holds a flame for his old team.

He spoke to Barometern in his homeland this week and the subject turned to Kalmar’s recent 1-1 draw with AIK – of which he had this to say:
“We played really well for the first 30 minutes, brilliant. Oops, I say we still.”
“It is a little as it looked during my time in Kalmar FF played really well in periods. But if it continues as the team will definitely climb in the autumn.”

For a moment it seems that Antonsson forgot he was in fact no longer a Kalmar player, but Leeds fans will surely not begrudge him this.
The Swedish striker seems a down-to-earth and talented striker who can hopefully adapt his game to the more demanding aspects of second-tier football in England.

He looks set to be used regularly throughout the season, as Leeds look to add more goals to their game – a factor that was lacking at times last season.
If Antonsson can discover his Swedish form in England then he will forget about Kalmar soon enough.
