The 25 year old will leave the MIlers after Stoke City have submitted an offer for the player which automatically triggers a release clause in the Swedish internationals contract.
Few can deny the popular keeper the chance to improve himself after nearly 4 years worth of fantastic performances with the club.
Here's a letter to the Millers fans from the Swede
I felt that it was only right to express my feelings in sincerely written words to you to thank you for everything that you have done for me over the last three-and-a-bit years.
It doesn’t feel two minutes since I arrived at AESSEAL New York Stadium in 2020 but it has flown by and now, after creating memories that will last with me forever, it is finally time to say goodbye.
I write this to you incredibly excited about what the future holds for me, but with the heaviest heart.
I was just a kid trying to find his way in football and in life when I signed during those uncertain days of the pandemic and I leave today feeling like thanks to this football club, I have matured immeasurably on and off the pitch. So much of that is down to the amazing people here at Rotherham United.
I still remember my first days at Rotherham United, which were spent in a hotel room in isolation, having been able to fly over for a trial from Sweden when the pandemic allowed. It was such an uncertain time for everyone and, of course, I wasn’t able to meet the supporters for much longer with fans having to watch games from home during that time, but the love and warmth that I felt from Minute One of becoming a Miller is genuinely something that I will treasure forever.
This has been the most incredible chapter of my career, but I hope that Millers fans remember it as an amazing period in the club’s history. Together we won promotion back to the Championship in a record-breaking season and we topped all that off with the joy of winning at Wembley in the Papa Johns Trophy. Staying up last season was another standout highlight. I learned quickly that we defy the odds as Millers and to do that with a group of my mates in that dressing room was euphoric. This year hasn’t gone how any of us would have liked. It hasn’t been for a lack of trying and I hope that my post-match interviews when I have been called upon have come across as genuine when I have spoken of the hurt which we have suffered with you. Sometimes football doesn’t give you a fairytale ending, that is how it is. With that said, the scenes of that final day against Cardiff City a few weeks ago will never be forgotten – and again were beyond my wildest expectations. A huge thank you must go to the Gaffer for how he handled the entire situation and for giving me that moment with you all. I am beyond grateful for that.
On the subject of staff, I want to use this opportunity to express my gratitude to everyone I have worked with. The goalkeeper coaches, Andy Warrington, Billy Mercer and Scott Brown deserve particular credit for helping me to progress. A massive thanks also goes to the managers I have worked with and all of my teammates, who haven’t been colleagues, they have been friends – many of whom I will stay in touch with for years to come. Everyone behind-the-scenes has always looked out for me, from the people you don’t see at Roundwood to those in the offices at the stadium. It would be remiss of me not to thank the Chairman Tony Stewart, for allowing me the chance to pursue this next opportunity in my career. It was his club that gave me a platform and he has been so gracious in not standing in the way of the next step.
I honestly don’t think any letters, interviews, video messages or anything else could convey how truly, truly grateful I am to you all. It has been a special time for me and my family and the kindness that you have shown us extends well-beyond any I could ever have expected from any football club.
The Viking hats, the Sweden flags, the way in which you have spent time with my dad, Tobias – I’m sure he owes some of you a couple of pints! - has all been overwhelming. It was said in the interview on the pitch after the last game, but I honestly fully-understand and appreciate the phrase ‘Once a Miller, Always a Miller’. This is more than a football club and I am immensely proud to say that I have represented you all.
