Here's all the news from around the Emirates Stadium over the past 24 hours.
Player ratings vs Olympiacos
Arsenal will feel they have one foot in the Europa League quarter-final after a 3-1 win over Olympiacos at the last-16 stage.
Goals from Martin Odegaard, Gabriel Magalhaes, and Mohamed Elneny secured a deserved first-leg win in Greece, although another defensive error allowed the hosts back into the game temporarily.
As a result, it is now nine games in succession across all competitions in which the Gunners have failed to keep a clean sheet.
But the good news is that they are well-placed to avenge last season's round of 32 exit at the hands of the Greek outfit and seal a place amongst the final eight.
As expected, Odegaard scored high in the ratings, as did defender Kieran Tierney who once again was a constant threat down the left-hand side.
But how did the rest of the team fare?

Pep Guardiola agrees with Mikel Arteta about VAR
Manchester City boss Pep Guardiola has joined Mikel Arteta in hitting out at VAR.
Despite seeing his side beat Southampton 5-2 on Wednesday evening, the Spaniard complained about Phil Foden not being awarded a penalty when seemed to be felled by goalkeeper Alex McCarthy.
In the process of falling, Foden attempted to lift himself back to his feet and scramble after the ball in an effort to score. As a result, VAR deemed McCarthy not to have fouled the Man City winger, much to Guardiola's - and many onlookers - disbelief.
"I don’t understand how Fulham disallowed goal against Tottenham," Guardiola told Sky Sports. "I don’t understand the hands from Arsenal against Burnley. And another example is the penalty today.
"Like we won, it’s incredible and happy and everything. But Jon (Moss) cannot see it. But the VAR is there.
"Don’t listen the penalty is incredible. You know that for a long time, for about four or five years, I never complain about the referees. But this action is really in-cred-ible, in-cred-ible.
"The same with Fulham and Arsenal, with the hands. Maybe, one day, they will explain to us really the rule for all the managers and the players."
Wonderkid signs contract
Arsenal youngster Hubert Graczyk has signed his first professional contract.
A statement on Arsenal.com reads: "The 18-year-old goalkeeper has made 10 appearances for our under-18s this season, keeping two clean sheets, and he recently made his debut for our under-23s against Liverpool.
"Graczyk has represented England at under-18 level and is known for his reaction saves and ability to play out from the back.
"We congratulate Hubert on his first professional contract and look forward to supporting him with his continued development.
"The contract is subject to the completion of regulatory processes."
Graczyk is the latest Arsenal youngster to commit his future to the club after Jordan McEneff confirmed over the weekend that his contract has been extended.
