Rangers manager Steven Gerrard to BT Sport: "We put a lot into Thursday night but we’re not going to use it as an excuse. This is a tough game and we’ll have to be at our best if we want the three points. We have to try to keep the same levels of hunger, keep the intensity up. If we have any ambitions of having a good season, we have to come to places like this at times when everything is against us and still perform and take maximum points."
