Middlesbrough boss Aitor Karanka admits they're strengthening their ties with Chelsea.
Chelsea defender Kenneth Omeruo, who played for Nigeria at the World Cup, has returned for a second loan spell on Teesside and Karanka is also chasing Stamford Bridge starlets Patrick Bamford and George Saville.
"It is not just because Jose (Mourinho) and I are friends," he said.
"Our relationship with Chelsea is good because it is healthy for all parties.
"Bringing in Kenneth is a deal that makes everybody happy because it works for all of us.
"Chelsea believe we are a good club to send players on loan to develop and grow because we have the same philosophy as Jose."
