Emery was the president of Arsenal and enjoyed a promising career in his first season. Currently, only two games have been lost in the Premier League.
Spain's president, Bernd Leno, Lucas Torreira, Sokratis Papastathopoulos, Matteo Guendouzi and Stephan Lichtsteiner all came in through the door, bringing in five new players in the first transmission window in the summer.
The arrival of Emery had a positive effect on the whole. Some games have a longer game time than other games.
But he still thinks the president of Sevilla will bring back the center back in January.
"I do not know, I do not really know." Palmer told Express Sports in response to a question asked by Emery about what sign he would sign in the new year.
"I'm sure he will be where he wants to be.
"In the center half he was probably stronger.
"But he [Laurent] Koscielny came back, but they missed him, but he's a bit older, but I think he's going to rate the situation in January so he's trying hard to get back.
"He'll hold people anyway."
One defender with Arsenal linked is Eric Bailey of Manchester United.
The Ivory Coast has not been featured since it was restrained in just 19 minutes after winning the Premiership title against Newcastle on March 2.
Manchester United have already scored 21 goals in the Premier League this season and compete with teams like Phil Jones, Chris Smallring, Marcos Rosjo and Victor Lindelof.
But Arsenal may be ready to suggest a fresh start to Ivorian when Mourinho should decide to ax him as the transport window opens again.
However, Emery wants to strengthen his defense options against Mauricio Pochettino in a match against Tottenham.
