Plymouth Argyle are reported to be facing competition from Oxford United for the permanent transfer of Charlton Athletic defender Alex Mitchell. According to Football League World, Oxford are 'eyeing up a move' for Mitchell, who spent last season on loan to Argyle and performed so well for them that he was the Supporters' Player of the Year award winner. Argyle head coach Tom Cleverley made it clear even before the end of the 2025/26 season that he was keen to bring Mitchell back to Home Park next term. The 24-year-old centre-back, who has one more year remaining on his contract at Championship club Charlton, also seemed open to the idea of a permanent move to the Pilgrims. However, given how impressive his performances were for Argyle it is no surprise he is now being linked with another team. Oxford's two-season stay in the Championship ended with relegation in May so they will be League One rivals for the Pilgrims next term. Football League World reported that Oxford are 'eyeing up a move' for Mitchell, who is expected to be a key player for the Pilgrims next season. The transfer speculation is likely to continue in the coming weeks as the summer transfer window approaches. Plymouth Argyle have a busy summer ahead of them as they look to strengthen their squad and prepare for the new season. The club will be hoping to make some key signings to help them push for promotion next season.
