Ghana defender Mohammed Salisu scored in the wrong net despite Southampton's impressive pre-season victory over Swansea City.
The 22-year-old, who has been excellent in pre-season, unfortunately turned in a Liam Cullen's cross into his own net to hand Swansea City a 15th minute lead.
However, the English Premier League side were too strong for the championship side coming back strongly to win 3-1.
Nathan Tella, Nathan Redmond and Stuart Amstrong scored for the Saints.
Salisu has featured in all three friendlies for the St Mary's outfit, playing against Fulham, Cardiff and now Swansea.
“It was a good game, I think, and we scored three good goals,” he said. “It’s a pity that we conceded one. It was a mistake from Sali [Salisu], but okay,” Southampton boss Ralph Hasenhuttl said after the match, as reported by his club's official website.
“We are in pre-season and I must say that we are physically in good condition. The last freshness was not there, but overall it was a good performance.
“We dropped the speed a little bit in the last 30 minutes. We had a few good chances, yes, but I hope that we can find the next gear and push them a little bit more.
“It was not enough for me, but after the week they’ve worked hard, and yesterday we didn’t really respect the game today because we still worked hard, so it’s okay.”
