I'm not really sure that Diego Simeone is under pressure from the clubs management, they still see him as the coach with the kind of aggressiveness that Atletico Madrid needs. His been in charge for over a decade now and seriously I don't see anyone replacing him at the moment. Some years ago, he was about to leave the team but the management convinced him to stay and till now his been there.
If he wanted to leave and the club had to convince him to stay then he must be a messiah to that club. I don't understand why they have to keep him for 10 years only to signed an additional 2 years contract, that will make him 12 years if he is able to complete the period and funny thing is he might not win any Laliga with this performance. Barcelona is too good to let go of that trophy, this season is already secured, only a matter of 36 weeks left before they take it again.
The club didn't even think of doing something about the third place they have consistently taken over the years, if Barcelona can do it and Real Madrid could do it, then there is nothing anywhere that can stop Atletico Madrid from winning it like the rest of the club. They need an upgrade but they have decided to roman Simeone for many years, until they break their self from his trap before they can grow further but if they think there isn't another tat can do better, then there is nothing for them.
