Chelsea midfielder Moises Caicedo is convinced his partnership with Enzo Fernandez can stand the test of time.
The pair have impressed at time this season, though the combination has also lacked consistency.
But Caicedo insists: "It's easy to play with him.
"We have the same language on the pitch and help each other. We enjoy when we win and we are frustrated when we lose."
The Ecuador international also said: "Personally, now I am feeling good. I can see my gains and I am playing better and helping the team. That is important for me because when I don't play well, I get frustrated.
"It's my first season at Chelsea so it's normal that it took some time and I am learning in every game."
