England coach Gareth Southgate as put Manchester City defender Taylor Harwood-Bellis on notice.
Southgate admits they're monitoring the youngster.
Discussing Manchester United captain Harry Maguire, he said: Harry's shown great resilience and his performance level with us through the season has been very, very good. It's been challenging for him, he's captain of a huge, worldwide football club and he's not been able to play so that would have been hard.
We want competition for everybody, definitely. John Stones has had an outstanding season probably since the World Cup to the end. It's a reminder for all players who are having a difficult period because he was having one leading into the World Cup. So he's finished strongly.
We like Marc Guehi, we've invested in him. Him and Levi [Colwill] are probably the two youngest in the league. For England future that's good. I am interested to see Harwood-Bellis in the Under 21s, to see what might happen with him next year."
