Dagur Dan Þórhallsson is an emerging Icelandic defensive talent currently showcasing his skills with Montreal Impact in Major League Soccer. Primarily a right-back, the 25-year-old brings a modern interpretation to the full-back role, combining defensive solidity with energetic forays down the flank. His career began in Iceland with Breiðablik, where his athleticism and crossing ability made him a standout in the Úrvalsdeild. His performances earned him a coveted move across the Atlantic to Montreal, where he has adapted impressively to the physical and fast-paced nature of MLS. With a market value reflecting his potential at €1.5 million, Þórhallsson is seen as a key part of his club's defensive unit and a player with significant resale value. He is strong in one-on-one duels, possesses good recovery speed, and provides consistent width in attack. His development in North America is being closely monitored back home, as he is considered a strong candidate for future call-ups to the Icelandic national team.
