'It's not a good relationship, it's a deal for money' - Emery on Villa-Chelsea moves

Unai Emery has insisted that there are no "good relations" between Chelsea and Aston Villa after a series of transfers between the clubs.

On Sunday Argentina goalkeeper Emiliano Martinez joined Chelsea from Villa, completing the eighth deal between them in the past four years.

Martinez's move to Chelsea comes after Nicolas Jackson's transfer the other way last week.

No two Premier League clubs have exchanged more players, on permanent or loan deals, in the past four years.

But Villa boss Emery said the relationship between the two clubs is "only through the deals for money".

"Good relations?" he said. "They want to kill us and we want to kill them!

"We have good players and we can sign one player off them, it's not a good relationship - it's a deal for money and a deal for players.

"I am happy for Emiliano Martinez and Morgan Rogers and I know I am not happy for Chelsea ."
