(Video) Diego Costa all-but ends Chelsea stint, parties and mocks Conte

As a result, the 28-year-old has been excused from the start of pre-season training with the Blues in the hope that he will be able to find a new club and resolve his future.

Rudiger, who was a member of his country's Confederations Cup triumph earlier this month, is with the club as they prepare for their preseason tour in China.

"It is a worrying situation because Chelsea need a striker in place", Canoville told Sky Sports.

Diego Costa has been dumped by Antonio Conte for the forthcoming 2017/18 season by text message.

Conte has been relatively quiet in the transfer market this summer, signing goalkeeper Willy Caballero and Roma defender Antonio Rudiger to this point.

Ben Gladwell reports on Serie A, the Italian national team and the Bundesliga for ESPN FC , UEFA and the Press Association. Transfer market expert Graham Hunter says striker Alvaro Morata should sign for Chelsea this summer.

Over the last few days the Spaniard has been mercilessly trolling his team-mates on Instagram. You need someone who's capable of holding the ball up and can finish.

Having developed into one of Europe's deadliest strikers at Atletico Madrid, Diego Costa made the move to Chelsea in 2014 and instantly became a fan favourite for his robust style and goalscoring exploits.

"Morata has also not been getting regular games at Real so he's bound to be a little rusty".

The striker was back to his best during the 2016-17 season, though, again hitting 20 Premier League goals to fire Chelsea to another title and taking his tally to 52 league strikes in 89 outings at the time of writing.

"Not to be disrespectful but we speak about Roma and Chelsea. I'm sure Chelsea will bring in the right players to help them compete on all fronts".
