Barnett ran riot in the wide areas with his exceptional crossing causing trouble for Northampton's defence. McClean's opener and Lee's third were assisted by Barnett while the full-back played key roles in the two other goals which led McClean to hail his performance as a "masterclass".
WHAT MCCLEAN SAID
After the victory, McClean took to Instagram and wrote: "3 points, 2 goals, assist, witnessed a @ryanbarnett38 masterclass, brilliant Sat at the Racecourse 🙌🏻🔴🐲".
