1. Arsenal pull it off, win FA Cup

You have to hand it to Arsenal. No other team has beaten Chelsea twice this season, but Arsene Wenger's players pulled it off in style by making Antonio Conte pay for his selection mistake with a 2-1 victory in the FA Cup Final.

This was a game that nobody expected Arsenal to win. They were facing the champions, a team chasing a league and cup double, and they were without three first-choice centre-halves, forcing Wenger to hand Per Mertesacker his first start in a year at the back. Yet despite all of the odds being stacked against them, Arsenal's fighting spirit and the brilliance of Alexis Sanchez were enough to overcome Chelsea and secure a record 13th FA Cup for the club.

As good as Arsenal were, Chelsea manager Conte gave them a helping hand by going for substance over style with his decision to start Nemanja Matic instead of Cesc Fabregas. Conte's tactic was clearly all about overpowering Arsenal, beating them with a sledgehammer rather than with flair, but it backfired.

With Conte's team starting slowly and sluggishly -- Sanchez's controversial opener came in the fourth minute -- the absence of Fabregas against his former team was critical. Matic and N'Golo Kante could not get a grip of midfield, which meant Eden Hazard could not influence the game further forward. Pedro and Diego Costa were therefore starved of service and Arsenal simply grew in confidence with every misplaced Chelsea pass or failure to do the basics.

As they did against Manchester City in the semifinal, Arsenal summoned something extra from somewhere, the missing ingredient that has seen them end the season in fifth place. But Conte's failure to make the right selection and get his tactics right may hint at the challenge he will face next season.

To build on Chelsea's title success, he needs to evolve his and his team's style to avoid being too predictable. Wembley suggested he has some work to do on that, but will he be prepared to do it?

Meanwhile, Arsenal win the cup again, and whatever happens with Wenger, he has delivered another trophy to the Emirates.

2. Forget Wenger as Sanchez should be Arsenal's priority

Arsene Wenger's future as Arsenal manager is the only story in town right now, with his contract expiring this summer, but the real priority at the Emirates should be putting the "Not for Sale" signs on Alexis Sanchez.

Enough time has already been wasted by Wenger and the Arsenal board in terms of resolving the manager's situation, and it will be in the best interests of everyone at the club for that issue to be dealt with as quickly as possible: maybe even within the next week. But Sanchez's future, rather than Wenger's, is what will define this summer.

Whether Wenger stays or goes, Arsenal have a battle on their hands next season to return to the Champions League and once again become contenders for the Premier League title. But after he produced another scintillating performance for the Gunners against Chelsea at Wembley, scoring the opening goal against the champions, it is clear that Arsenal quite simply cannot allow Sanchez to leave this summer.

The Chilean may be out of contract in 12 months' time, which carries the real risk of him leaving for nothing next year if Arsenal hold him to his contract now. Manchester City, Chelsea and Bayern Munich are all prepared to pay in excess of £50 million to sign Sanchez, but he is worth far more than that to Arsenal. Without him, Arsenal can forget about a top-four finish next season, but if he stays and top quality players arrive to bolster the squad, anything is possible next term.

Persuading him to stay, maybe against his will, will be a tough challenge, but Arsenal are a big club and now is the time to act like one.

3. Referee gets it right with Moses red card

Well done, Victor Moses, who became the first player to be sent off in an FA Cup final for diving. It is not an enviable distinction, but the Chelsea wing-back can have no complaints over referee Anthony Taylor's decision to issue a second yellow card on 68 minutes after he threw himself to the ground in the penalty area after an Alex Oxlade-Chamberlain challenge.

Towards the end of the Premier League season, instances of diving (or "simulation," to give it its more palatable name) increased dramatically. Marcus Rashford and Leroy Sane were both involved in high-profile diving incidents, and both got away with it. But Taylor was on the spot to deal with Moses, and he showed no hesitation in sending the Nigeria international off.

Although Chelsea quickly bounced back from the loss of Moses to score an equaliser through Diego Costa, Arsenal then broke down their left -- the flank Moses was patrolling -- and Olivier Giroud crossed for Aaron Ramsey to restore their lead.

The red card left Moses embarrassed and shamed, but it also cost his team dearly in a cup final. Next time, a player may think twice about the consequences before diving to win a penalty.
