Russell Martin admits Swansea City have a "real problem" with defending set-pieces following their loss to Reading.
The Swans dictated the majority of the contest at the Select Car Leasing Stadium but fell behind as Andy Carroll rifled into the net from a Tom Ince free-kick.
Ince then netted his side's second after a sloppy pass from Steven Benda, before Liam Cullen scored what proved to be a consolation for the Swans, who are now winless in eight matches.
