Ahead of the weekend's clash with Premier League newcomers Bournemouth at Upton Park, Italian defender Ogbonna is looking to return to the winners' list for the good of the playing group as well as the claret and blue faithful.
"We were very annoyed on Saturday because we know we have the quality. We need to think about the next match and make the fans happy again," the summer signing told the club's official website.
"This is football because sometimes things do go wrong, but we have to fight and carry on and forget about this result and focus on the next game. We have one week now to cool down and prepare.
"We were very solid against Arsenal. The whole team did very well. We did not do badly [against Leicester], everybody defended and attacked but it's just the result that was disappointing and we are annoyed at that."
