Arsenal thrashed Nottingham Forest 5-0 at the Emirates on Sunday to return to the top of the Premier League, but the win may have come at a cost after Bukayo Saka limped off midway through the first half. 

Saka’s replacement Reiss Nelson scored a brace to go with goals from Gabriel Martinelli, Thomas Partey and Martin Odegaard. But the injury to the winger will be a major concern for manager Mikel Arteta and his England counterpart Gareth Southgate three weeks ahead of the start of the World Cup in Qatar. 

Arsenal move to 31 points from their 12 games, two ahead of Manchester City, while an outclassed Forest remain rooted to the bottom of the table with nine points having played a game more.
