However, the Japanese defender was injured again in their previous game against Newcastle United on May 16 and has been deemed unfit to play in today's crucial game.This saw the Gooners take to Twitter to rage about the star's unreliability and constant fitness struggles, with some demanding that the club sell him.Here is a selection of tweets from Arsenal fans:S4V@LacaSavvvCan we just sell TomiyasuCan we just sell Tomiyasu𝗗𝗮𝘃𝗲 @xDaveAFC@Arsenal @BukayoSaka87 Tomiyasu out again… can we reinforce this guys legs please 1@Arsenal @BukayoSaka87 Tomiyasu out again… can we reinforce this guys legs please 😭Sakanelli14@Sakanelli14We defo need a new RB, tomiyasu isn't reliable enough these days.

Man is a figment of our imaginationIs Tomiyasu even real? Man is a figment of our imaginationThe right-back has been a vital piece of Mikel Arteta's defense, but injuries over the course of the season have seen him play just 21 Premier League games. The injury against Newcastle will see him miss the last match of the season.Arsenal will have to remain focused and hope they can take all three points from Everton in a last-gasp attempt for the remaining Champions League spot. The fifth-placed Gunners will need to beat Everton and hope that Tottenham Hotspur lose against Norwich City to finish in fourth place.Arsenal's flurry of exits could continue in the summerThe Emirates Stadium has seen quite a few exits from club stars over the last 12 months, and that could continue as the league heads into another transfer window.Last summer, the Gunners saw the last of players like Willian, David Luiz, and Joe Willock. In the winter transfer window this January, former club-captain Pierre-Emerick Aubameyang exited the club, alongside players like Calum Chambers and Sead Kolasinac.Players like Alexandre Lacazette, Eddie Nketiah, and Mohamed Elneny will see their contracts expire, and they could also leave the Gunners this summer. So it's expected that the higher-ups at the Emirates Stadium will be working on replacements.With the club fighting for a return to the Champions League, they will need a number of fresh, prolific faces under Mikel Arteta's guidance before the new season commences. There have already been numerous reports of their interest in Manchester City star Gabriel Jesus, as well as reports of links to Barcelona's Memphis Depay.In the meantime, the Gunners will have to hope they can snatch Champions League qualification from Tottenham Hotspur's grasp.
