Icelandic international Jón Daði Böðvarsson has left Reading to join Championship rivals Millwall for an undisclosed fee, the club has confirmed.

The 27-year-old forward joined the Royals in the summer of 2017 from Wolves, going on to score 17 goals in his 56 appearances for the club.

Böðvarsson last found the net for us in a 2-2 draw away at Brentford at the beginning of last season.
