Bjorn Runstrom admits a calf injury is hampering his attempts to make an impact at Fulham.

The 22-year-old joined the Premiership side from Hammarby in the summer, but has yet to establish himself.

Though Fulham have scored just 13 goals in 12 league games, Runstrom has been restricted to a solitary eight-minute cameo against Tottenham.

Runstrom concedes he has become frustrated at his inability to force his way into Chris Coleman’s plans on a regular basis.

But the forward acknowledged that a nagging calf complaint has not aided his claims to be involved in the squad.

“It’s nothing serious,” Runstrom told Expressen about his injury. “I have played with minor injuries before, but in the end the calf didn’t stand it. At times, you should maybe rest after the first blow, but it is difficult to stop playing. It is tough to earn a place in the side, but you have to work on. In the end, you will hopefully get more playing time.”
