With Boulding nearing his best again, Groves paid tribute.
"Michael's shown his prowess with regards his heading, the He's scored two goals over the last two games and he's not renowned for his heading. At this moment in time he's looking a real threat."
The right sided combination of Jason Crowe and Marcel Cas also came in for praise from Groves. Crowe reverted back to full back for the game with Cas in his more natural wing slot.
"I thought Jason was excellent today," Groves continued. He's played against a lad who's quick and I think they've swapped him around at half-time because Crowie's snuffed him out. His use of the ball has been excellent, so I'm delighted for Jason.
