There was nothing extra ordinary that the coach did. I don't also think they had ego, I felt they've realized how important it is to qualify for the World Cup, so they don't want to give room for excuses anymore, from the first half, you could see how desperate the likes of Victor Osimhen, Ademola lookman and the rest forwarders where pushing forward the ball, until they secured that first two goals in the first half.
You may be thinking that the only small work the super eagles coach did was as he was calling and telling them what to do, he did a lot you did not realize, the coach should be the most celebrated because without him the super eagles may not win because a player cannot select other players that will be on the match, actually to tell you how important he is, this world Cup we want to go can only be possible through this coach you think are not doing anything, actually I have been fortunate to play a community local football to practically see what coaches covers, from fixturing, Substitute, encouragement, conflict resolution, unity and wining, so what do you think he should have done to prove that he was the key to the wining?.
One thing i learnt is knowing when to give credit to coaches and players. The game against Rwanda was totally inspired by the coach, the formation used was something we haven't seen before, the players did well but it is only just the tip of an iceberg managed by Eric Chelle, the players looks very comfortable, a friendly environment within coach and players will contribute massively to the success of how they perform on set to win games.
If any team has a wrong coach then no matter how good the players under the team are they can't win games, a better coach with an average team can do better than potential players and a wrong coach, coaches are more mentally than physically creating impact on players.
