Playing away in the Champions League, it is always going to be tough, but I think with Gyokeres, you can feel the difference when he is playing compared to when Kai Havertz is. "Arsenal created chances before that and Gyokeres created a chance or two himself, but Arsenal just felt like a different team when Havertz was in there, maybe because there were some more familiar faces coming on to the pitch as well, the likes of Christos Tzolis and so on, but they looked different and it felt different, it felt more familiar."
