Diego Costa ensured Arsene Wenger's 22-year reign as Arsenal manager will end in Huddersfield and not Lyon as the former Chelsea man hit the winner for Atletico Madrid in a closely fought Europa League semi-final.

Five things we learned

When Arsenal lost 3-0 at home to the best team in England, four days after losing in the Carabao Cup final, there were some onlookers who described it as rock bottom. Now that statement is looking both over-ambitious and lacking in foresight.

Man City 3 - Arsenal 0: Pep Guardiola has his first trophy as manager of Manchester City and Arsene Wenger may have won his last in charge of Arsenal after the Premier League leaders dismantled their rivals 3-0 in the Carabao Cup Final on a day of bitter contrasts.

Arsenal 4 - Crystal Palace 1: An emphatic first win of the New Year does not definitively prove there is a bright future for Arsenal without Alexis Sanchez but manager Arsene Wenger confirmed his players had been destabilised by the uncertainty over the Chilean’s transfer to Manchester United.

Arsenal duo Mesut Ozil and Laurent Koscielny have an outside chance of returning from injury to face Chelsea on Wednesday.

West Ham 0 - Arsenal 0: Arsenal missed an excellent chance to get back into the Premier League top four as they made it three games without a win for the first time since last April.

“We’ll be punished if we play like this on Saturday.” It’s not often the crowd at the Emirates grumbles in agreement, but that was the general sentiment in N5 just before 9pm last Wednesday.

Arsenal 5 Huddersfield 0: The Herbert Chapman derby ended in an emphatic victory for the more illustrious of his two former clubs.

Burnley 0 Arsenal 1: Alexis Sanchez kept his composure to defeat Burnley with a last-minute penalty, again, but an important Arsenal victory that lifted Arsene Wenger’s side into the top four also offered a painful vision of their future.

Harry Kane is among a number of Tottenham players set for late fitness tests ahead of Saturday's north London derby against Arsenal at the Emirates Stadium.

Laurent Koscielny will start the long journey of putting his FA Cup final heartbreak behind him when he returns from suspension for Arsenal tomorrow.

France 3 - England 2: Not even the controversial use of video assistant referees could prevent Gareth Southgate’s England from succumbing to defeat in their season-ending friendly against France.

It felt like one of those slow-motion car-crash moments when Koscielny recklessly clattered into Valencia during last Sunday’s climax to our league campaign.

If this was the end, it was the perfect final chapter. Should Arsene Wenger bid au revoir to North London this week he will do so having guided Arsenal to their most unlikely FA Cup success of his 20-year spell in charge.

Arsenal are likely to be without Granit Xhaka for their Premier League clash at home to Manchester United on Sunday.

Usually the rare sight of two teams with a pair of Double Gameweeks in a row would have FPL managers gleefully doubling or even trebling-up on both. Not this time.

Arsenal 2 Man City 2

Tottenham 2 Arsenal 0: After describing how proud he was of his Tottenham Hotspur side’s performance in a one-sided north London derby, Mauricio Pochettino was asked whether Chelsea’s victory at Everton earlier in the day meant there was an underlying feeling of disappointment in home dressing room at White Hart Lane.

As we sat basking in the glorious Wembley sunshine yesterday, it felt strangely unfamiliar to be beaming with satisfaction with the game still goalless at half-time. 

Arsene Wenger admits he does not know who captained his Arsenal side for the second half of their draw with Manchester City.

Usually I’d be positively bristling with anticipation at the prospect of getting round to the Arsenal, in the gorgeous spring sunshine, following the comparative purgatory of a fortnight’s international break.

Arsene Wenger will still be in charge when Arsenal play at West Brom again next season.

Arsene Wenger declared himself "revolted" by referee Tasos Sidiropoulos' performance in his side's 5-1 Champions League loss at home to Bayern Munich tonight.

Arsene Wenger saw Arsenal humiliated again as their 10 men crashed out of the Champions League after another five-goal mauling at the hands of Bayern Munich.

A trio of former Arsenal stars have turned on Arsene Wenger and his players after a humiliating 5-1 Champions League thrashing at Bayern Munich.

Bayern Munich 5 - 1 Arsenal

Premier League

Arsenal 2 Burnley 1

Swansea 0 Arsenal 4: Arsenal’s Petr Cech is confident a collective effort from the chasing pack will keep the pressure on runaway Premier League leaders Chelsea.

Arsenal 1, WestBrom 0: Relief. It’s lucky Arsenal have a hold over West Brom, having only lost once in 12 previous meetings with the Baggies.

West Ham 1 Arsenal 5: ALEXIS SANCHEZ is either playing for a move, or a new Arsenal contract. 

Sunderland 1 Arsenal 4: Arsene Wenger is the manager renowned for not seeing pivotal incidents during a match, but it was David Moyes who appeared to be watching a different game on Saturday.

Arsenal 6 Ludogorets 0: Bash out another win like this in Bulgaria in two weeks time and Arsenal will have all but qualified for the knock out stage of the Champions League for the 16th year running.

Arsenal 3 Swansea 2: The final Premier League table is normally a mirror of each club’s wage bill, which is one of the reasons Arsenal are not being tipped by many to win the title this season.

Shkodran Mustafi felt Arsenal displayed the "steel" required to mount a sustained Premier League title challenge this season after Laurent Koscielny's bizarre stoppage-time goal had snatched a 1-0 win at Burnley.

Theo Walcott’s epiphany, 10 years after first arriving at the club and at the grand old age of 27, that he is a winger not a striker inspired Arsenal to a Champions League victory over Basel and, coming just three days after a fine victory over Chelsea, has raised levels of positivity at the Emirates to new levels.
