But Chelsea, Tottenham, Manchester City and Liverpool fans have also suffered disappointment when reported targets have failed to materialise.
Arsenal have beaten Chelsea in their last two clashes with the Blues, in the FA Cup final and Community Shield at Wembley.
"I think Chelsea have a genuine chance of winning the Champions League", Merson wrote in his Daily Star column. They are one player short of being virtually unstoppable. If Chelsea go a goal up, you know Arsenal will capitulate.
Obviously these figures will change as the season unfolds, but as of now Morata has played seven more league minutes than Lacazette and he has been far more productive, registering three goals and two assists compared to the Frenchman's two strikes.
Despite only giving the slightest push, Lacazette showed his class by going to check on his opponent and offering him help to get back to his feet.
"I watched him come on as a sub in the first game against Burnley and even in that 15 minutes..."
The Frenchman somehow managed to fire the ball over the crossbar from a few metres out after good work from Aaron Ramsey which left his coach Arsene Wenger looking in disbelief from the touchline.
The strikers arrived in the Premier League as record transfers for their clubs in the summer as Morata joined Chelsea from Real Madrid for £65 million, while Lacazette moved from Lyon to Arsenal for £52 million. It's like when you watch something and someone's done something in 15 minutes and you think 'wow, they can play' and he done that about five times.
