Southampton boss Claude Puel has put Jack Stephens on notice.
Puel handed England Under-21 cap Stephens his first start in his preferred position of centre-back against Norwich, but remained coy on whether the 22-year-old is yet ready to step into Jose Fonte's shoes.
Refusing to confirm Saints would chase a replacement for Fonte, Puel said: "It was important to see him in his main position of centre-back, having had a couple of starts at right-back.
"It's interesting to see Jack Stephens in this situation for example.
"Because we know Jose Fonte's situation, he might leave the club, so it's important to see Jack's performances."
