Goals from Paolo Di Canio, Fredi Kanoute and susbstitute Jermain Defoe - his first ever Premiership goal - were nothing less than Hammers deserved for a hard-working and impressive performance at Portman Road.
Speaking just moments after the final whistle, Glenn said: "It was great to get our first away win of the season today. Ipswich is a very difficult place to come and get something but I felt we thoroughly deserved the victory.
"We did some work on the 3-5-2 system in training the last two days and the lads carried it out perfectly. I am especially pleased for the two lads who were making their first appearances of the season - Hayden Foxe and Scott Minto. I asked Scott if he'd ever played on the left of a back three before and he told me that he'd played there a few times for Benfica. I couldn't disprove that so I had to believe him!
"There was some terrific football out there from us, some really good passing and, to be honest, we could have scored more than three.
"Michael Carrick, who was magnificent, hit the crossbar with a fantastic shot and Fredi Kanoute probably could have got another one. That's five goals for him now, though, and he was awesome today.
"I said to him after training yesterday that I would have hated playing against him when I was a centre-half. He is so big and strong, and technically excellent as well.
"He was great today - they all were - and I was very pleased for young Jermain Defoe, who deserved his first Premiership goal.
"We'll enjoy today and enjoy training this week, but we've got a hard game against Fulham next week and we will need to have our feet back on the ground for that one.
"I haven't got any players who get carried away with a victory but we will make sure they are all fully focused on trying to make it four successive wins next Saturday."
