Southampton's Carlos Alcaraz has been "feeling guilting" about injuring himself celebrating his goal against Leicester, said boss Ruben Selles.
The Argentine midfielder is a doubt for Southampton's visit to Manchester United on Sunday after damaging his knee while sliding after his goal.
The 1-0 victory lifted Saints off the bottom of the Premier League for the first time since November.
"It was the emotion of the moment," Selles said of the 20-year-old.
Alcaraz had to be replaced early in the second half of the United game after being unable to run off the injury.
