Paul Merson fears for Arsenal's Premier League title prospects if they're forced to rely on Eddie Nketiah while Gabriel Jesus is out injured.
While Mikel Arteta's side can move eight points clear of Manchester City at the top of the table if they beat West Ham on Boxing Day, Merson thinks they'll struggle to even make the top four without properly replacing the Brazilian.
Jesus injured his knee during the World Cup and is expected to be sidelined for three months, with Arteta acknowledging this week the club would have to be 'active' in the January window.
