Chelsea boss Graham Potter admits how Enzo Fernandez settles will be key to him fulfilling his potential.

The Argentine trained today following his switch, although will not be fully acclimated. But when he is up to speed and integrated alongside Chelsea's other January signings – and key players returning from injury – Potter is optimistic about what can be achieved this term.

"Like I often say, signing players is relatively easy, signing the right ones isn't. Then we need to align everyone together so we're all on the same path and all going forward," Potter explained.

"There is potential [that the new signings change what is possible]. That's why we're excited. But at the same time, we also have to respect the fact a team needs to come together, we need to gel, we need to work and go day by day.

"But certainly, there is excitement for that. We're excited with the players we've added, excited for the players returning from injury and when you look at the group it's a really strong, competitive group."
