Ex-Chelsea midfielder, Gus Poyet says the club must sign a “special” player in the January transfer window to avoid “going backward.” He also warned the Blues to be careful not to upset their promising youngsters.

Due to a two-window transfer ban, Frank Lampard was unable to sign any players in the summer. However, that was reduced on appeal meaning players can now be signed.

“The transfer window will be very important,” Poyet said.

“Everything is all very good at the moment in the club. But this is Chelsea. He is the manager of Chelsea and at this club, you need to get to certain points. This transfer window could be key to that.”

“You need o bring in a very special player. But you cannot upset the atmosphere. You cannot take away one of the youngsters because otherwise, you contradict yourself.”

“At the same time, you need something to help you get better because something is still missing there. There are some very important decisions to be made.”

Chelsea has been linked with a move for a striker. Reports suggest Oliver Giroud is set to leave.

On this matter, Poyet added, “If Giroud leaves, probably he will bring someone in.”

“I don’t know how the staff is looking at Michy Batshuayi-if they are seeing him as a replacement if Tammy Abraham can’t play.”

“But then the question is who do you bring in? if you bring someone to play you will upset Tammy.”

“It is tricky but you have to add. If you stand still you go backwards because the rest keep moving forward. So, you have to be very careful.”

“Eriksen’s situation needs resolving at Spurs.”

A club likely to be active this month is the Tottenham. Christian Eriksen has been strongly linked with a move away from Spurs for a while now.

Poyet believes Eriksen’s situation needs to be resolved quickly to enable both the club and the player to move on.

“I have been watching Christian and something is not right.” Said Poyet.

“He is not the Eriksen of two years ago. He is not affecting the game in the way he was affecting it.”

“I think they need to sort it out. I didn’t see Christian Eriksen happy in the FA Cup game with Middlesbrough and I didn’t see the fans happy with him.”

“It is something that needs to be sorted soon for the best of everybody.”
