Speaking to Sky Sports News, Yoro said: "I think it's been difficult for everyone. This game is in the past now and we need to move forward and think about Burnley. The team is ready to hold their heads up and we're looking forward to the game.
"It's difficult because I think without the Grimsby game - against Fulham and Arsenal I think we were a bit unlucky in these games because we did well, honestly. We had the opportunity to score and we conceded goals we can avoid - I think these are the small things we need to improve. If we don't concede these little mistakes, we will win games - it's just little mistakes we need to change.
"Once we enter Carrington, we focus on ourselves and the spirit of the team. The team spirit is really important for our team and we saw in pre-season when we were always together - we built a spirit. This type of game [Grimsby] helps also to have a good spirit because we need to stay together no matter what the result is. We need to reflect this on the pitch and try to do everything to do it."
