Despite reported interest from Paris Saint-Germain earlier this summer, Diego Simeone opted to stay put at Atletico Madrid.
Having signed a five-year extension worth £4.4 million-per-year in 2015, the Argentine decided to respect his contract at the Vicente Calderon, much to the delight of his players.
Upon committing his future to Los Rojiblancos, he said: "I have chosen to stay here because the club is growing.

"It is strong and that fills me with enthusiasm. In life it is difficult to choose sometimes but I am sure about the decision I have taken."
PSG would eventually hire Sevilla's Unai Emery and, two months on from rejecting a move to the Parc des Princes, it would seem Simeone might regret that decision.
What's most significant about Simeone's planned departure, though, is how it will effect Antoine Griezmann's future in the Spanish capital.
The France international has an excellent relationship with his manager and recently revealed how he would only leave Atletico if Simeone did.
"The only doubt would be if Simeone leaves for PSG or wherever," he told Telefoot, per Goal.
"I called him before extending my contract and he confirmed to me that he was staying. I can learn a lot from him."
All this could be great news for Manchester United and Jose Mourinho, who are long-term admirers of Griezmann and have identified the Frenchman as their number one transfer target for next summer.
Mourinho's interest reportedly stems from a number of failed bids as Chelsea manager and that he believes Griezmann would be a "sensation" in the Premier League.
Two years is a long time to wait for one player but, considering the 25-year-old's talents, he might just be worth it - even if he would cost a world-record fee.
