Pellegrino is counting on their FA Cup win at West Brom to be a sign of things now improving.
“I am focused. I feel focused and feel like I want to help my players to try and be better to find a different solution on and off the pitch to be better in this amazing challenge," he said.
“I feel I'm trying to find different ways to approach mentally different moments and I feel the mental strength will be the most important thing come the end.
“Every single team will have ups and downs in the Premier League. Technically or tactically you can make some bad decisions or mistakes but mentality will be the most important thing."
“My job is stressful because you need a lot of energy and you've got to be focused, but I am enjoying my job. But it's a big challenge at this moment," he added.
