We are down to the last two groups tonight when G and H are decided and the final four teams of the Russian Federation 2018 World Cup last 16 go through. I don't think mentally we lose anything because they know we've made changes and they know Belgium weren't their full team.
Amid suggestions Belgium did not want to win, Adnan Januzaj's second-half strike sealed victory and left England second.
By winning the match and thus the group, Belgium moves to the "side of death" for the knockout round, where four of the top five teams in the world according to Federation Internationale de Football Association rankings - Brazil, Belgium, Portugal, and Argentina - will all compete for one spot in the final. We know it's early on in the process of what we're trying to do, but this is just a chance to try and prove it today.
"This was a game we wanted to win but the knockout is the biggest game for a decade for us, and we had to make sure our key players were preserved", Southgate said.
The Colombia coach said he was "extremely concerned" about the player's fitness but was pleased that the team rose to the occasion to snatch the win against Senegal.
Manchester City's Delph has been given permission by England boss Gareth Southgate to temporarily leave the nation's training camp, though is expected to return ahead of the round-of-16 clash with Colombia on Tuesday. He said: "We talked about momentum".
He said: "The most important thing for me is the players are in the best physical condition for the game". "It would not be hard to see England drawing and that game going to penalties".
"I'm a little surprised because everybody seems to be happy in England, thinking they are now on the right side of the World Cup draw because they've avoided the half with Brazil", said Eriksson, who believes his countrymen will see off Switzerland to set up the showdown with England.
"It was a good test with the double objective, with half an eye on the knockout rounds".
It was a very different end to Group G, where England and Belgium both seemed intent on finishing second, gambling on the runners-up spot delivering a smoother route into the tournament's latter stages. It didn't happen for them tonight, but we don't suffer for it.
