Mikel Arteta has ruled William Saliba out for Arsenal's game against Leeds - but is "very hopeful" he will be fit at some point before the end of the season.
The Gunners currently sit eight points clear of Manchester City at the top of the Premier League and have a very good chance of winning their first top-flight title in 19 years.
However, Arsenal have been dealt a massive blow ahead of the run-in. Saliba, who has been excellent this term, will miss the clash with relegation-threatened Leeds through injury.
