LONDON — Arsenal suffered a shock 2-1 home defeat to Bournemouth, denting momentum ahead of their Champions League second-leg against PSG. Declan Rice marked his 100th appearance with an opener, but goals from Dean Huijsen and Evanilson sealed Bournemouth’s first-ever away win at Arsenal. Mikel Arteta admitted his side fell short defensively and urged his players to channel their frustration in Paris on Wednesday. Meanwhile, Aston Villa boosted their European hopes with a 1-0 win over Fulham, thanks to Youri Tielemans’ early header, extending their home unbeaten run to 20 matches. Villa are now level on points with Chelsea and Nottingham Forest in the top-five battle.
