Chelsea manager Jose Mourinho has said he wasn't surprised by Diego Costa's call-up to the Spanish national side, and indicated the striker will play his third game in eight days against Arsenal on Sunday - though he admitted it's too much.
Costa played for the Blues against Aston Villa last weekend, and in midweek against Sporting Lisbon in the Champions League. Despite ongoing concerns over a hamstring injury - the Chelsea manager is prepared to play him on Sunday against the Gunners.
He also confirmed that both Didier Drogba and Ramires will miss Sunday's clash.
Speaking at his press conference ahead of the game, Mourinho said: "My reaction to the news he is in the Spanish squad is no reaction because it is something I could already imagine.
"I'm not going to save him for the national team.
"This week we had three very important matches, the champions league match was crucial for us. After a bad result for us at home [against Schalke], it was a crucial victory [against Sporting Lisbon]."
It's the first time the two sides have met since Chelsea hammered Arsenal 6-0 at Stamford Bridge in March in the Premier League - but Mourinho is anticipating a very different type of game this weekend.
He added: "The 6-0 is once every 50 years. It's not year after year it's something that happens occasionally.
"Can we win again? Yes we can, but it's a very big match against a big team, and a very difficult one.
"It's once in a life, it's not normal. Chelsea-Arsenal, normally, the result is close."
He also took the time to congratulate Arsene Wenger on 18 years at Arsenal, and commended the club for their part in the Frenchman's reign.
"It's an amazing achievement, congratulations to him and to the club.
"It has also to do with the club philosophy, I congratulate both Arsenal and Mr Wenger."
