Aribo was in fine form as Rangers bounced back from their disappointing League Cup final defeat to Celtic last weekend.
The visitors took the lead just before the half-hour mark through Nikola Katic’s thumping header from a Borna Barisic corner.
Rangers continued to press for the second goal after the restart and eventually doubled their lead on 69 minutes as Alfredo Morelos swivelled inside the area before burying a left-footed shot into the bottom corner.
The visitors finished the game with 10-men after Morelos was sent off in the 71st minute.
“It was very pleasing. We’ve had a tough week, mentally and physically so you were wondering what type of performance you were going to get but credit to the players I thought across the board we were really good, really organised,”Gerrard said after the game.
“If there’s one fault I’d have it was not capitalising on some of our good play when we were 1-0 up to go and kill the game earlier. But it’s an away win, a clean sheet on the back of a tough week so I’m very pleased.
“I think he [Alfredo Morelos] was looking dangerous, he was causing their centre-backs a lot of problems, I thought he had good backup in Joe Aribo who was sensational today and I felt as if it [the goal] was going to come.
“But unfortunately, this is probably his first minor misbehaviour since he’s turned a massive corner. So that’s probably the only disappointment from today.
“We’ve got no complaints [with the red card]. Look, he’s a human being, he’s young and I must admit he’s doing everything he can to improve in that area. That’s probably his first setback but we’ll reset him and go again and we have no complaints,”Gerrard added.
