Belgian striker Jelle Vossen gave Boro the lead, finding space in the Brentford area and planting a header into the bottom corner. 

A mix-up in the Boro backline gave Andre Gray the chance to level things up for The Bees, but Fernando Amorebieta struck late on to give Boro the all-important lead to take back to the Riverside a week later.
