Chelsea boss Mauricio Pochettino offered a mixed review for Mykhaylo Mudryk after their 2-2 draw with Arsenal.
The Blues were 2-0 ahead via a Cole Palmer penalty and a Mudryk freak goal before Arsenal's fight back.
Pochettino said, "I think he is playing well but also he needs to improve still. For me he is not at his best. I think we needed to change and to put a bit more of pressure on Nicolas Jackson up front. After that situation, we created a few chances and I think the game was closer to 3-0 than 2-1.
"I think the chances, Palmer and Nico. I think we want to keep a little pressure and not only say okay, we are going to protect the result. But in the end, when we change with Reece and Noni, two minutes before that we concede a goal. It was a little bit unlucky that is the type of situation that happens in football and we feel sad but in another way we are very positive because we showed great character and personality and the team performance was really good.
" Too many games that we watch every week and always mistakes. Football is about mistakes. If you want to score, the opponent made a mistake. I think 90% of goals are because the opponent made a mistake when you score. Football is about mistakes. I think only we can criticise a little to read the situation better, the tempo, the timing. 77 minutes, sometimes take some risk. Okay, we can, because it's our philosophy but maybe have better decisions. Maybe we can criticise a little bit this situation."
