Arsenal collapse 3-0 at Brighton: Arteta calls it a big lesson

Three goals conceded. Seven straight wins before that. A big lesson. Arsenal left the Amex with their first defeat of the season, and Mikel Arteta did not look for an excuse. He called it a big lesson, a message delivered right after Brighton completed a 3-0 demolition. Before the match, Arsenal looked like the most frightening team in Europe in the early part of the season. After ending a 22-year wait to reclaim the English title, they opened the new campaign with seven straight wins in all competitions. Not many expected Brighton to stop that machine. But football does not reward reputation. Brighton pressed high from the first minute, suffocated Arsenal's buildup from the back, and when they won the ball, they did not hesitate to shoot from distance. Pascal Gross opened the scoring. Charalampos Kostoulas doubled the lead before half-time. Early in the second half, Chema Andres out-jumped everyone to head in from a corner and make it 3-0. Arsenal's usually resolute defence was breached three times in three different ways: two long-range strikes and one aerial duel. Arteta said: 'Extremely disappointed. Brighton deserved the victory. They were the better team. From our side, there were certain basics you need to accomplish in football, especially in the Premier League, and we were very far from that.' Arsenal fans might comfort themselves that this was just one bad match. But Arteta's tone showed he took the issue seriously. It was the first time in more than three years Arsenal lost a match by more than two goals. For a team built on solidity, that is a telling number. The story does not stop at Arsenal losing. The more important point is that they lost while being regarded as the most likely champions. Rivals will watch this game as a map of how to beat Arsenal: press high, block passing lanes, force them to defend in open spaces. If these weaknesses are not fixed, they will be exploited again as the season reaches its decisive phase. Arteta also mentioned the World Cup context: 18 players came back, they played a lot and won many matches. But he made it clear: 'This is a big lesson for all of us to understand what it takes to win at this level.' That sounded more like a warning than an excuse. The three-week international break is a window for Arteta to repair the damage. He needs to find out why the defence looked so fragile and why the team lost its 'basics' in a big match. Arsenal still have every chance in the title race, but the lesson from the Amex will follow them for the rest of the season.
