Arsenal head coach Unai Emery has analyzed his side’s  3-2 win against West Ham. According to the Spanish coach, the Gunners must go on working hard and use all chances as they did today. “We are happy with the first three points after two defeats against Manchester City and Chelsea. “We needed a win today and we needed to show our supporters. The three points were the first objective. It’s clear we need to improve, to continue working and not concede as many chances like we did today. “Why is the reason tactically we conceded that? We will look at analysis to improve this. “Maybe today, the first half we wanted to use the right-back and left-backs in attacking moments, but we needed balance with the midfielders. The first half we conceded a lot [of chances] from this option. “Our first goal was from this action, Hector crossing for Nacho, but we didn’t do the balance for the transition. We suffered a lot, but we won.
