Harry Maguire, the man nicknamed Slab-Head by his team-mates, headed England into the lead over Sweden with a towering header.
Dele Alli then netted the second as England ran out 2-0 winners to book a World Cup semi-final place.
Maguire just missed out on the official man-of-the-match award to Jordan Pickford but his display didn’t go unnoticed by his team-mates.
After celebrating on the pitch at the final whistle, Walker returned to the dressing room to post a picture of Maguire talking to girlfriend Fern Hawkins.
He wrote: “Yeah so a good header doesn’t hurt. I mean the moment you head it proper, you feel it’s a good one. Know what I mean love?”
The message was retweeted more than 35,000 times within two hours.
Former captain Alan Shearer lauded England's "professional" and "thorough" performance after they beat Sweden 2-0 to book a place in the last four for the first time since 1990.
Gareth Southgate's side will now face Russia or Croatia in Moscow on Wednesday night.
Shearer said on BBC One afterwards: "Amazing. What a performance. Professional, thorough. Every single player played their part.
"(Jordan) Pickford was outstanding in goal when he had to be. I thought Harry Maguire was superb, (Jordan) Henderson...what a shift he put in in midfield. John Stones, Deli got his goal. All of them were absolutely magnificent and thoroughly deserved it.

"Their attitude from the very first moment they arrived at this World Cup to now has been first-class and I didn't ever feel anything other than we are going to win this game, we are going to get to a semi-final.
"I never felt nervous at all during the game and that is how comfortable they made us feel."
He added: "I thought coming into the tournament that we could get to perhaps the quarter-final, but they have just got a momentum, a team spirit that is just dragging them through, and I thought it was their best performance tonight.
"They were so comfortable, they managed the game superbly well, they did what they had to do, they saw the game through and it was very, very thorough and professional."
