Graham Potter’s men shrugged off the Turkey Lig 1 side’s advances and wrapped up the game in the closing stages of the encounter after Jamie Hopcutt - on for Gero as an 81st minute substitute - weaved past defenders to give the Jämtkraft Arena outfit a two-goal advantage heading into the second leg of the tie.
The former El Kanemi Warriors marksman was cautioned in the 18th minute. And he hopes to help his side seal progress to the next round of the Europa League qualifiers when they visit the Türk Telekom Stadıum for the return leg on July 20.
