Saracens defence and forwards coach heaped praise on his young guns who helped steer the Men in Black to a 38-21 victory over Leicester in the LV=Cup.
Tries from Jamie George, Duncan Taylor, Joe Maddock and Andy Saull gave Sarries an imperious 27-0 lead at half-time and while the second half was a more even affair, the hosts were comfortable throughout.
Gustard's men were playing at Bedford’s Goldington Road which was their 11th different venue of the season.
“It was a brilliant first half in which our youngsters really came to the fore," Gustard said.
"Ben Ransom was instrumental in that first half and Duncan Taylor, the local boy come good, did really well as well.
“Saracens often get criticised for not playing attacking rugby but we showed we do play attacking rugby when the conditions allow.
“Knowing Leicester, their culture and their coaches and Cockers (Richard Cockerill) being a vociferous young character at the best of times we expected a response and unfortunately for us we allowed them to come back into the game a little bit.
“We slipped off a few tackles and our mistakes helped them get back in it. John (Smit) isn't a bad sub to bring on and at that time I felt it was important to get his experience on there to shore things up despite how well Jamie George was playing.”
