Chelsea winger Callum Hudson-Odoi has turned down the chance to play for England U-21s, prompting former Manchester City star Trevor Sinclair to berate him.The 20-year-old Chelsea star has enjoyed excellent form for Thomas Tuchel’s side over the last few weeks. But despite his recent performances for the west London side, Hudson-Odoi still could not do enough to secure a break into Gareth Southgate’s England senior squad for their World Cup qualifiers against Albania and San Marino.Nizaar Kinsella@NizaarKinsellaTuchel isn't concerned with Hudson-Odoi's lack of England selection/U21 snub: "If Callum is here, we have full control with what he is doing, full control of his load, his focus and his approach to his game.

Trevor Sinclair has slammed the star for refusing to play, asking him to "look in the mirror." Sinclair said: "Hudson-Odoi, he refuses to play for the under-21s, and I'm thinking, 'How do you even do that? As soon as you get called up for the under-21s, go and play. There's a good chance that half that under-21 squad will be your teammates in the first team anyway."So I just can't understand why Hudson-Odoi won't play. He did some great stuff for Chelsea in Europe in the last few weeks, so why isn't he in the under-21s? He must be looking at lads that he probably supercedes who are getting England caps, and he's not getting any. Have a look in the mirror, young man."Hudson-Odoi is still eligible to represent Ghana, and rejecting the chance to play for the Under-21 side might leave an opening for the Black Stars. The Chelsea star’s decision also displeased Southgate, who believes Hudson-Odoi has missed an opportunity by turning down the call-up."We are constantly watching him" - Southgate on Chelsea star Hudson-OdoiMalmo FF v Chelsea FC: Group H - UEFA Champions LeagueSouthgate has revealed that Hudson-Odoi is determined to force his way into the senior squad with his performances at Chelsea. He said:“He has had a couple of good matches for Chelsea. I know Thomas [Tuchel] is guarded about how much he goes with praise on that but it is good to see him back playing and playing more regularly at first-team level and he knows the challenge that’s ahead.“But he knows also that we are constantly watching him and he is young and talented enough to mount a serious challenge as we move forward.”Chelsea FC@ChelseaFCOi, Oi, Oi, Hudson-Odoi. 💙11:24 AM · Aug 11, 2021458014811Oi, Oi, Oi, Hudson-Odoi. 💙 https://t.co/v3xGvZt9pmHudson-Odoi will be hoping to keep up his impressive start to the season and give the England manager a reason to push him into the senior squad.
