The 21-year old was assisted by Chelsea teammate Ruben Loftus-Cheek and also lined up alongside two other young Blues, Nathaniel Chalobah and Kasey Palmer, the latter of which making his debut. Baker was one of the stars of the show and ended up scoring the all important winner for Gareth Southgate's side, while posing a threat all evening.
Midfielder speaks following win
After the game, the midfielder spoke about his performance and also lauded England's strength in depth, something they will need with three games in the next five days.
Baker said that whilst he was happy to score, "the three points was the main thing", and that he was proud that his team "pulled through" to start off with a win.
He went on to hail the squad itself, saying that they "have the squad to change things aroud" which will come into play as the tournament progresses.
"As we saw [against Portugal], the subs came on and made a difference and it's the same throughout the squad - we have good strength in depth and that's what we're going to need," said the youngster.
Can England come through to win?
Baker's goal against Portugal adds to a solid season he enjoyed while on loan at Vitesse Arnhem and he'll be hoping he can continue to perform well for both club and country.
The U21s face Guinea on Monday night, before facing Paraguay on Wednesday and Japan on Friday to finish the group stages. Southgate's men will need to win all their remaining fixtures to reach the final of the tournament and Lewis Baker will be hoping he can be a large factor in helping get to that stage.
