Gareth Southgate called on supporters to stick with the players after some England fans booed the team following the lacklustre goalless European Championship draw against old rivals Scotland.
Having impressively beaten World Cup semi-final foes Croatia on Sunday, the Three Lions knew they would progress to the knockout phase with a game to spare by winning Friday's auld enemy showdown.
But uninspired England fell well short of expectations against the wounded Scots, with John Stones' early header off the woodwork the best they could muster in a 0-0 draw at a partially filled Wembley.
Scotland made life tough under the arch, with Stephen O'Donnell denied superbly by Jordan Pickford in the first half and Lyndon Dykes seeing an effort cleared off the line in the second period.
But the main emotion is frustration and captain Harry Kane's ineffective display a concern, with the 27-year-old hooked in the 74th minute to compound Sunday's underwhelming display against Croatia.
"I think the whole team, we have got to look at the whole performance and our use of the ball and review where we can be better," Southgate said when asked about his skipper's performance.
"That's right across the board, so it's not just about one person.
"Scotland, I thought, marked him extremely well. With the back five there isn't a lot of space and of course anything that was played up they were aggressive, they defended well.
"Tonight we couldn't find the answers. We've got to go away, review the game and find those answers for the game with the Czech Republic."
