Arnesson is a defensive defenseman with a lot of careful, secure actions in his playing style. His skating is smooth and he is a heads up player who is mobile and concentrates on shutting down the opposition. He is very good skating backwards with strong lateral movement and does a good job of reading space. Arnesson can be a tiger in his own end and uses his quick first step and sound agility to put on the heat opponents in his own end, particularly in the corners. He is not much of an offensive defenseman but his first pass is good and he can identify passing options.
Arnesson returned to Sweden on loan to Djurgarden in the 2014-15 season, joining Bruins' AHL affiliate Providence after Djurgarden was eliminated from the SHL playoffs in early March. Still fairly early in the development process, he should continue to develop as he matures physically and makes the adjustment from the larger rinks in Europe to North American hockey. His size and playing demeanor suggest Arnesson can be an effective shutdown defender at the NHL level one day.
