This story has significance for readers across Kenya and beyond.

- Jose Mourinho went viral after sprinting towards Denzel Dumfries during Real Madrid's opening La Liga match against Espanyol

- The animated moment came as Dumfries took too long over a throw-in while Madrid held a narrow one-goal lead

- A new five-second countdown rule for throw-ins was introduced across Europe's major leagues this season, including La Liga

Jose Mourinho has turned heads once again, this time with a sprint along the touchline during Real Madrid's season-opening 2-1 La Liga victory over Espanyol.

The 63-year-old returned to Los Blancos for a second spell in charge, and while his reaction to the match-winning goal was composed- a clenched fist followed by a measured walk along the touchline- it was a separate incident that caught everyone's attention.

Why Mourinho charged at Dumfries

With Madrid protecting a slender lead late in the match, Netherlands international Denzel Dumfries was slow to restart play from a throw-in.

Referee José María Sánchez stepped in to signal the countdown, and Mourinho wasted no time doing the same, dashing over to Dumfries to urge him to act quickly.

What Is the New Throw-In Countdown Rule?

The reaction from Mourinho was rooted in a genuine rule change that came into effect across Europe's top leagues at the start of this season. Under the new regulation, a five-second countdown begins if a player takes too long to restart play from a set-piece, including throw-ins.

Should the five seconds expire before play resumes, possession is handed to the opposing side — a significant enough consequence to send any manager scrambling to the edge of his technical area.
