Arsenal's defensive issues continue to pile-up, leaving Mikel Arteta with a headache going into ties against Rapid Vienna, Manchester United and Leicester City, but he may well have the solution staring him right in the face.

During the warm-up prior to kick-off against Manchester City on Saturday afternoon, Rob Holding suffered another injury setback as he pulled up with a hamstring problem. He was replaced by David Luiz.

According to the Daily Mail, the 25-year-old is set to be out for the next three to four weeks, meaning Arteta may only be able to call upon his Brazilian duo, Luiz and Gabriel.

He, of course, also has William Saliba, who is yet to make his Gunners debut since a £27m move from AS Saint-Etienne a year ago. The young Frenchman was loaned back to the Ligue 1 outfit for the season and will be part of the first-team set-up - at least until January where things can be reassessed.

The Athletic's David Ornstein claimed the 19-year-old would be named in Arteta's Premier League squad over Mesut Ozil, so perhaps it's time to call upon his exploits.

And if there are any doubts, then the Arsenal boss ought to look at their next league opponents for inspiration, the Foxes.

Brendan Rodgers threw Saliba's former ASSE teammate Wesley Fofana straight into the deep end at the weekend with Caglar Soyuncu absent through injury.

The club-record €32m (£30m) signing, who is also only aged 19, picked up the highest rating of any Leicester player (7.2) as they were defeated by Aston Villa 1-0 at the King Power Stadium.

Per SofaScore, Fofana made nine clearances, three tackles, three interceptions and won 87.5% of his aerial duels. He was an absolute beast, despite the conceded goal.

The fact that Saliba was argued as the better prospect between the two should be more than enough encouragement for Arteta to start him in their upcoming fixtures.

Fofana has even called his friend a "super player" who is "capable of succeeding in the Premier League," as per L'Equipe via Tribuna.

His former coach Fabio Frasconi once claimed: "William Saliba will go far, very far. He reminds me of Raphaël Varane" whilst ex-ASSE teammates Yohan Cabaye and Mathieu Debuchy have also waxed lyrical about him to the Official Ligue 1 podcast.

"I think he is a great player. He’s strong, with good technique. He’s quick, too. I think he has a lot of quality to play at Arsenal," lauded the latter.

Playing him will be far better than making him watch from the stands, Arteta must turn to Saliba during Holding's absence this week.
