Arsenal have confirmed that Takehiro Tomiyasu will miss the rest of the season after sustaining a serious knee injury during the Gunners' clash with Sporting CP last Thursday.
The right-back limped off in the ninth minute of the Europa League last-16 second-leg tie after he injured himself lunging into a tackle. Tomiyasu, who was replaced by Ben White, left the Emirates Stadium in crutches and Mikel Arteta didn't sound confident when asked about his condition.
After the game, he said: "Tomiyasu looks pretty serious from his reaction straight [away] and what he said to me, but obviously, it's very early." The Japan international played no further part in the penalty shootout defeat against Sporting and was also forced to sit out of the Gunners' 4-1 win over Crystal Palace on Sunday.
