Arsenal finished a memorable Premier League season with a comfortable victory at a scorching Selhurst Park.With the title already wrapped up in mid-week, the main question was: How heavily would Mikel Arteta rotate his side ahead of the Champions League final against Paris Saint-Germain next weekend?And that was answered emphatically. Arteta made nine changes to his Arsenal side, with the inclusion of Max Dowman seeing the midfielder become the youngest player to start a Premier League game.Despite the changes in south London, Arsenal secured a relatively easy 2-1 victory, with goals coming from Gabriel Jesus and Noni Madueke on either side of half-time. Palace did try to make a comeback of it, though, with Jean Philippe-Mateta halving the deficit before Yeremi Pino saw what he thought was a late equaliser ruled out for offside by VAR.Still, with both sides firmly focused on their hunt for silverware in Europe next week, the game was perhaps of little importance for many.Now, for Arsenal, those celebrations can begin…Art de Roché analyses the action on the day Arsenal would lift the title.Finally, Arteta has the opportunity to rest key playersOpportunities to truly rest key players have been scarce for Mikel Arteta this season, so it was not surprising to see him jump at the chance to do so for his side’s coronation at Palace.The Arsenal manager made nine changes to his starting line-up, and while it allowed squad players to get recognition for their efforts this season, keeping his main men fresh for next week’s Champions League final had to be done.Arsenal’s opponents for the final, Paris Saint-Germain, have been able to do this throughout the knockout stages of the Champions League. Between PSG’s 5-4 semi-final first leg win over Bayern Munich and their 1-0 second-leg victory, Luis Enrique made nine changes for a league match against Lorient.That week, Arteta marvelled at the football on display in the first leg, but said: “When I look at the amount of minutes and the freshness of those players, then I’m not surprised.“To deliver those moments of quality, you have to be very fresh. And the difference in the league and the way they are competing is night and day. We are competing in two different worlds.”Nine Arsenal players have played 2,000 minutes or over in the league this season, compared to three for PSG.
