But the second half was much better, we controlled the game much more.”The performance was, especially in the first half, not as good as we’ve had so many times this season.”But we’ve been on the wrong side of the score after a good performance far too many times and today, I think we got more than we deserved.”A draw would have been a fairer result than for us to win it.” Alexis Mac Allister struck in the dying moments of added time | GETTYSlott added: “Since VAR is there, I always struggle to celebrate too much if I think there might be something going on.”You never know, if a ball is hit to a body, where it ends up. And apparently it ended up on his arm.”So it was disallowed. So then my emotions were, ‘Okay, still not everything that could have gone against us this season has happened yet. Still one more to go’.”But maybe fortune has changed as two or three minutes later, we thought we scored the winner again. They took a long time to check it, but this time, the referee pointed at a kick-off, which meant we won the game.”Five facts about the Premier League | GETTY/GBNEWS/PALiverpool were forced to change their line-up before kick-off after Florian Wirtz struggled with back pain during the warm-up.Slot added: “We don’t think it’s very serious, but he felt his back too much during the warm-up to start, he wasn’t able to be 100 per cent or even close to 100 per cent.”After being in this league for six, seven or eight months, he now understands that no matter how rich you are on the ball, you need to be 100 per cent at his level, so we decided not to play him.”We hope and expect that he will be able to be with us again next week, but you never know how things work out.”
