Premier League champions Arsenal continued their winning start to the season with a 1-0 victory at Aston Villa thanks to Bukayo Saka’s close-range strike.In a game of few chances, Saka’s poked finish from Riccardo Calafiori’s cross broke the deadlock in the 59th minute — the first attempt on target from either side.Shortly before the goal, the visitors were awarded a penalty when Saka was bundled over by Ian Maatsen, but the decision was overturned after a VAR review, as replays showed the contact was outside the area.For Villa, this was a significant improvement following their opening-day 4-0 thrashing against Brighton & Hove Albion, but they are still pointless after two matches.The game finished just over 24 hours before the transfer window closes. So, will it have changed either manager’s plans? And what else did we learn?Amy Lawrence and Jacob Tanswell analyse the key talking points.Was this more evidence that Arsenal have work to do in attack?The list of coveted attackers Arsenal have monitored is well documented. In a slow and stodgy first half, it was blatantly obvious why the idea of signing Vinicius Junior or Julian Alvarez has been so prominent in Mikel Arteta’s thoughts.With a day of potential transfer activity left and the exits of Gabriel Martinelli and Gabriel Jesus expected to be confirmed, the burden on new winger Christos Tzolis looked heavy. This was a far more challenging introduction to the Premier League than a sunny showing at home to Coventry City last weekend. Aggressive tackles, some attention from the referees, and a cheap booking meant he was replaced by Eberechi Eze at half-time.The left wing might not be Eze’s favoured posting, but he was influential in breaking the deadlock. He waited in a dangerous space, progressed a move quickly to Calafiori, and Saka burst in to score.Martinelli, Jesus and Leandro Trossard made a total of 130 appearances last season, registering 45 goal contributions (25 goals plus 20 assists). Will the combination of Tzolis and Eze on the left, with Max Dowman probably playing more, fill that gap?
