Brussels proved to be a hostile meeting ground for Jose Mourinho on Thursday night, as the Chelsea manager was given a frosty reception by the Stade Roi Baudouin crowd.
Boos rang out for the Blues boss when his face was shown on the big screen as he watched Colombia battle to a 2-0 victory over their Belgian hosts.
Rafael Hernandez confirmed the jeers:
Per the Daily Mail's Thom Drake, the home crowd was not happy with the way Mourinho has treated Kevin De Bruyne in recent months, the young midfielder appearing for his national team on Thursday evening.
De Bruyne has struggled for first-team action at Stamford Bridge and is likely to find himself heading out on loan during the January transfer window, per Jamie Sanderson of Metro.
As the report suggests, the Portuguese also used his time to source some new material on supposed transfer targets, the visitors' Radamel Falcao ranking among the biggest.
Per Drake's report:
The 27-year-old (Falcao) scored the first when he beat the offside trap and curled his shot past Liverpool's Simon Mignolet.
Mourinho is an big admirer of Falcao and may make an offer to tempt him to Stamford Bridge in January. However, both Manchester United and Real Madrid are also interested.
As well as a personal scouting trip, however, Mourinho was on hand to keep an eye on the numerous Belgians in Marc Wilmots' team who have ties to his club.
While De Bruyne and Eden Hazard each earned a starting place against the Colombians, on-loan pair Thibaut Courtois and Romelu Lukaku lined up on the bench, the latter coming on for Christian Benteke with 15 minutes left to play.
Both Belgium and Colombia qualified for next summer's World Cup in fairly confident manner from their UEFA and CONMEBOL groups, respectively.
This season, De Bruyne has made just four starts across all competitions, and his cameo in the Champions League win over Schalke last week was his first senior appearance in almost two months.
Despite this, it seems the young playmaker remains a respected figure in his national spectrum and one Wilmots is still willing to utilise irrespective of recent form.
The rousing display of support for their player might affect how Mourinho uses his player in future.
Then again, knowing Mourinho, he will have departed the stadium unaffected.
