Arnautovic emphatically struck West Ham level
Marko Arnautovic fired home in the second half to give West Ham's survival chances a boost, bringing them level in their league match against Arsenal at the Emirates.
Nacho Monreal had opened the scoring shortly after the interval in Arsene Wenger's first game since announcing that he will be leaving at the end of the season.
However, Arsenal's lead lasted just 13 minutes as West Ham hit back to give their Premier League survival a boost.
Opposing goalkeeper David Opsina punched a cross from the left away but only into the path of the visitors.
Manuel Lanzini then prodded the ball into Arnautovic on the left who powered a finish low across Ospina and into the far corner to make it 1-1.
