Arsenal boss Mikel Arteta has promised to be proactive in next month's transfer window as the club look to find a replacement for Gabriel Jesus.
Jesus picked up a knee injury during Brazil's group game against Cameroon at the World Cup, and is expected to be sidelined for around three months.
His injury setback is a big blow for Arsenal, after he netted five goals in the first part of the season to put his team five points clear at the top of the Premier League table.
While Arteta refused to be drawn on exactly how long he would be without Jesus for, he admitted that the Gunners will need to bring in a suitable alternative to keep their title challenge alive.
