Saliba returns to Arsenal training after injury

Arsenal's 25-year-old French centre-back William Saliba joined first-team training on Tuesday, ending an absence of about four months caused by a back injury.

The player has not yet featured this season because of an injury he suffered during the World Cup. Trying to manage the problem throughout the tournament, Saliba was substituted in the 30th minute of France's semi-final loss to Spain, who went on to win the title. He was not included in the third-place match, which France lost to England.

Arsenal lead the Premier League after nine matches, three points ahead of Manchester City. The team has also gone three Champions League matches unbeaten. To strengthen its defensive options, the club has signed English defender Ezri Konsa from Aston Villa. The 29-year-old has performed well since arriving at the Emirates.

Arsenal host Czech side SK Slavia Prague in the Champions League on Wednesday.
