His West Ham teammate Michail Antonio was a guest on Goals on Sunday, and was asked about the global future of his teammate. "In the position he's in, at the age of 19, he's going to be 20 tomorrow, I don't think there's much people better than him in that defensive, holding position".
In-form Manchester United, meanwhile, are level on points with Arsenal after maintaining their 100 per cent record under Ole Gunnar Solskjaer with Sunday's 1-0 win against Tottenham at Wembley. "We need consistency over 38 matches", he said.
West Ham are interested in Bournemouth striker Callum Wilson as a potential replacement for Marko Arnautovic.
"We have won with him, we have lost with him, he is not one player that is for sale".
"It's our challenge. Each match is our challenge away", said the Spaniard. They send little messages to us supporters and everybody who is watching that they have to work out. The most important thing for us is to recover our confidence'.
"And then sometimes we are doing but like today [Saturday] we need to do more to be more competitive and to impose our idea and our quality".
Emery left Mesut Ozil out of his matchday squad for the trip to West Ham despite the playmaker returning to training following an injury.
But Emery instead opted to play Granit Xhaka alongside Matteo Guendouzi in the central midfield area, with Alex Iwobi and Alexandre Lacazette playing in support of Pierre-Emerick Aubameyang.
"The players who were here are the players who deserved to be in this match", added Emery after watching an Arsenal defeat that sees them remain fifth in the Premier League.
"He is improving in every game he plays, he is now more used to giving us a good build-up in front".
