Arsenal manager Mikel Arteta will soon have a selection headache now that star defender William Saliba has returned to training. The France international has been sidelined since July, having undergone surgery on a long-term back problem.Saliba is back on the grass in a huge boost for Arsenal – but what does it mean for Konsa?GettyThe France centre-back has not played since the World Cup semi-finals and his absence led to the Gunners’ £55million move for Ezri Konsa.Signed from Aston Villa, the England star has made an immediate impact, most recently helping Arsenal keep three consecutive clean sheets in the Premier League.However, Saliba is widely considered one of the top-flight’s best defenders, and he is now closing in on a return.But could there be room for both Konsa and Saliba in the same starting XI? Manchester United legend Rio Ferdinand has suggested Konsa could move to right back once Saliba is back full-time.Speaking on his YouTube channel, Ferdinand said: “I think Saliba is one of those guys that you have to find room for in the team. He’s that good, he’s top. “I said to my son yesterday, ‘watch Ezri Konsa’, because everything he does is efficient. That’s a great problem for Arteta to have.“I wouldn’t be surprised if Konsa goes back to right-back once Saliba comes back. I wouldn’t be surprised because Konsa is top.”Beyond his Arsenal form, Konsa has established himself as a first-choice option for England, starting seven of their eight games at the World Cup.However, Saliba and Gabriel were a huge reason for the Gunners’ Premier League title last season after a 22-year wait.Konsa has slotted in for Saliba superbly – ensuring Arsenal remain the Premier League’s most fearsome defenceAFPThey only conceded 27 league goals across the entirety of last term and Saliba was named in the PFA team of the year for the fourth consecutive time.Konsa at right-back?Usually, Ben White or Jurrien Timber start in the right-back position for the Gunners.But Konsa has shown the versatility to play there throughout his career. At Villa, he deputised for Matty Cash at right-back on numerous occasions under manager Unai Emery. Meanwhile, both Gareth Southgate and Thomas Tuchel have deployed Konsa as a right-back for England when necessary. Most recently, the Arsenal defender came to the rescue for England in the 2026 World Cup quarter-final against Norway when Jarrell Quansah was suspended and Reece James was not fit to start.
