What was also clear, though, was the fact Koeman will not tolerate the slipping of standards and the focus on the meeting at Finch Farm, Everton's training base, will be to remind the senior members of his group of their responsibilities to help end this slide.
Blind said: "I don't need to describe what kind of player he is and how important he is for the team".
'A young talent of 18 or 19? Ok. Sandro hasn't shown much as of yet but needs time to adapt and has also only just returned from injury. But of course, yesterday night I was really disappointed in the way we lost in the first 45 minutes. I wasn't so anxious after Chelsea.
Atalanta, a side stripped of their best players in the summer, with defender Andrea Conti and Frank Kessie joining AC Milan among other departures, scored three times in the first half against Everton. "I'm just going to say they're a team with incredible investment", Mourinho said of his opponent, the Toffees. "He's and Everton player now and he's one of the players who needs to react and bring the level of the players we expect from players like Wayne".
"[Atalanta] showed more aggression, they showed more passion". There was a big difference'.
"They're waiting for a real chance to start matches and to play from the beginning".
"I'm not going to analyse in that perspective", Mourinho said. I know how we have to defend him. He's very strong in the box, he's very good with his head, so he gives a lot of options for the man on the ball.
"If we defend like we have the last few games, maybe it's his afternoon". Everton are winless in their last four matches in all competitions, including two straight losses in the English Premier League.
"When you are injured it is always frustrating".
Stealing the show instead was Papu Gomez, whose curling effort for Atalanta's second goal gets all the headlines, stepping up when his team needed him the most after their return to European football.
Rooney (or Schneiderlin) could become the eighth different player to score against Manchester United having already played for them in the Premier League (Hughes, Dublin, Ince, Gillespie, Berg, Campbell and Welbeck).
