"We don't know if he is leaving, but for us it would be a huge loss!"

The future of Diego Costa at Chelsea is up for debate and will remain so right up to the end of the transfer window a month or so into the new season. With reports that Diego Simeone has demanded his signature for Atletico, we sit and wait to see what is going to happen.

With Chelsea's difficult year putting an end to a run of qualifying for the Champions League every year to bed and now we face a year without any form of European competition. With the prestige the tournament has, it has become the place that all the big names what to be involved. With the likes of Atletico waiting in the wings it's clear that Chelsea and Antonio Conte would do well to hold onto him.

We all love Diego Costa when he is on form and scoring goals. Yes he has had his troubles over here and suffered a massive dip in form as with everyone else last season but, he stuck to it, took on board the advice of Guus Hiddink to not get involved with the ball out wide, to focus on his job and he really kicked on in the second half of the season and scored goals on a regular basis.

I have said it before, the fact that he hasn't learnt the language here worries me. It's been two years and he still cannot speak English or refuses to do so in public. You can only put that down to not settling into life in London. Of course I am purely speculating but I am doing that because I can really see him going back to La Liga if Atletico or one of the other big clubs comes in for him. Back home to La Liga where he has felt his most comfortable and to a side in the Champions League next year.

Pedro has spoken out of the Costa rumours and he believes it would be a massive loss if he was to leave. He said:

"We don't know [if he is leaving], but for us it would be a huge loss. We want him to stay and we are going to see what happens with him."

It doesn't look good does it despite reports that Antonio Conte has met with him on more than one occasion in recent weeks.

Diego Costa was left out of the Spanish squad for the Euro 2016 competition starting this week and that would have been a blow to him. I just wonder if he thinks that he needs to go back to La Liga to get back into contention.

If Chelsea are going to force their way back into the top four then we need to hold onto our best players. Diego Costa without question is one of those players!
