Rangers defeated Hibernian 2-0 at home in the Scottish Premiership playoffs on Wednesday evening.
The right-back was at the Clyde Auditorium to see Hollywood legend Al Pacino earlier this week when a fan made what The Sun describes as a “sly comment”.
The 29-year-old has not stated the exact term the Rangers supporter used, but he has claimed that it was that remark which drove him to a brilliant performance against Hibs in the first leg of the playoff semi-final at Ibrox in Glasgow.
“I was out last night seeing Al Pacino,” Foster told The Sun. “It was really good and I got a ‘nice’ comment from a fan when I was there.
“I’m not going to divulge what the guy said, it was one those passing comments. He was feeling a bit gallus because he was standing with a couple of his mates and I was there with my girlfriend.
“So I hope he was watching tonight and enjoyed the game. That’s what comes from playing with Rangers. Criticism is not nice, but sometimes it spurs you on and gives you that determination to prove people wrong.”
Foster was a key player in the Gers’ 2-0 win against visiting Hibernian, setting up Nicky Clark’s opening goal just before half time and then standing strong at the back in the second period.
Over the course of the 90 minutes, Rangers had 53% of the possession, took six shots of which five were on target, and earned one corner.
Hibs had 47% of the possession, but the visitors took eight shots of which only one was target and earned 13 corners.
The second leg of the playoff semi-final will be held at Easter Road on Saturday. Rangers will head into the game as favourites, as they have a two-goal lead.
However, the Gers should not get complacent. If Hibernian get an early goal, then it could become tough for Stuart McCall’s side.
