Signing the right player in January is notoriously difficult but thanks to technology, the right player every club needs in January.
According to the Supercomputer created by Ai Abacus, Chelsea need to sign a holding midfielder in January and the ideal signing for the Blues is 21 year old German midfielder Adrian Fein.
Fein is currently on loan at PSV Eindhoven with an option to buy from Bayern Munich.
The Supercomputer credits PSV and Chelsea with a similar playing style, which means Fein will fit into the system at Chelsea well.
He is also expected to pair strongly with Ziyech, Jorginho and left back Ben Chilwell.
