Rangers-linked winger Oskar Fallenius has revealed he was forced to call security on his own fans as tensions mount over his expected January departure from Djurgardens.

Fallenius, 25, was named as a target for Rangers last month, with the Glasgow giants understood to have been keeping tabs on his progress in the Swedish top flight, with his contract expiring in December at the 3Arena.

While Rangers are reportedly expecting a quiet winter transfer window following their heavy spending during pre-season, the former Sweden youth international is reported to be one of the names on the club’s list of potential targets, with Fallenius registering five goal contributions in 10 games for Djurgardens and available on a Bosman free transfer when the January window reopens.

An important player for the Swedish giants, frustration over his rumoured departure has boiled over in recent weeks, with the player audibly booed by sections of the club’s support during the warm-up against Gothenburg recently. He has now confirmed that the fans’ comments became so heated, he felt forced to turn to security staff at the stadium to calm the situation.

“I just wanted to show our security officers that it was not okay, and of course they agree,” Fallenius told Swedish outlet Aftonbladet. “It was special, but I still think I was able to handle it quite well. Criticism is one thing and I can take that. It's part of playing for a big club. But the incident itself was something I couldn't tolerate. But we in the team have had a good dialogue, so it's nothing that's weighing on me too much, but it was important that we brought it up."

Meanwhile, interest in Rangers’ prolific frontman Ryan Naderi is believed to be ramping up ahead of the January transfer window. Several reports say clubs in England are monitoring the situation of the Czech international striker. Signed for £5million from Hansa Rostock last January, he struggled to impress at Ibrox initially, but has exploded into life this season, scoring nine goals and assisting a further five in 17 games across all competitions.

Taking full advantage of his chance after injuries to Lawrence Shankland and Youssef Chermiti saw him allowed to lead the Rangers frontline, his prolific form has not gone unnoticed across the border, with EFL Championship promotion chasers West Ham United and Wolverhampton Wanderers reported to be mulling over a megabucks deal in the new year, alongside an unnamed team from the German Bundesliga.

According to a report from TEAMTalk, both Naderi and Rangers teammate Olwethu Makhanya have been scouted at Ibrox in recent weeks. Currently on a 12 game unbeaten run in all competitions, however, it is understood the club has no intention of allowing any of their star men to leave in January, with the Ibrox hierarchy determined to ensure they don’t disrupt their momentum mid-season.
