Atletico Madrid boss Diego Simeone has extended his contract with the Spanish side until 2020.

The Argentine's work over the last couple of seasons has made him one of the most in-demand managers in European football.

Manchester City and a host of Italian clubs were all believed to have approached Simeone over the last couple of months, but the 44-year-old has ended all speculation surrounding his future by signing a new deal until 2020.

Simeone led Atletico to their first La Liga title since 1996 last season, while the capital outfit also made the final of the Champions League.

It is also understood that Simeone has been promised funds to improve his squad this summer.
