Dyer started the 2010–11 season with strong performances, including during the new coach Brendan Rodgers' home match for Swansea City: a 4–0 rout against Preston in which Dyer scored one goal and set up a goal for David Cotterill. His second goal of the season came when he scored the opening goal in a 4–3 victory over Middlesbrough on 12 February 2011. His form was sustained throughout the campaign, and he was eventually named Swansea City Supporters' Player of the Year 2010–11. Dyer played an important role in the Football League Championship's play-off final in which he made a double assist, for both Stephen Dobbie and Scott Sinclair, in a 4–2 win over Reading. That victory earned Swansea a promotion to the Premier League, making them the first Welsh club to ever play in the league.
