Arsenal legend Martin Keown has warned defenders William Saliba and Gabriel Magalhães that they ‘can’t make mistakes’ as the Gunners prepare to face West Ham United in the Premier League this weekend.
Arsenal will host the Hammers at the Emirates Stadium following their 2-1 victory over Newcastle in their last Premier League encounter.
Both Saliba and Gabriel have forged a strong defensive partnership for Arsenal in recent seasons.
Speaking on TNT Sports, Keown said: “Mosquera, the new acquisition, is really top draw.
“He has the same DNA as [Saliba and Gabriel]. Kiwior perhaps did not. He was not as quick or as strong.
“It is a high level [now] and [Mosquera] will push [Saliba and Gabriel] to play even better. They can’t make mistakes.”
Arsenal are currently second in the Premier League table, behind leaders Liverpool.
