Russell Martin believes Swansea City's priorities in the summer transfer window became clearer after their emphatic 5-1 loss to Nottingham Forest.
Steve Cooper's men struck four times in the second half after Michael Obafemi had cancelled out Jack Colback's opener in the opening 45. Defeat brought an end to Swansea's impressive nine-game unbeaten run.
Forest ended the contest having had 17 shots on target, with a further 10 off target, despite seeing just 30% of possession. Martin admitted post-match that he had learnt a lot about some of his players after their capitulation in Nottinghamshire.
