Chelsea manager Jose Mourinho may be one of the most recognisable faces in football, but he still would have hoped to remain inconspicuous during a scouting mission to watch Monaco striker Radamel Falcao on Thursday.
Unfortunately for Mourinho, however, he attracted plenty of interest while sat in the stands of the King Baudouin Stadium, and was roundly booed by Belgium fans during the friendly encounter with Colombia.
Mourinho appeared on the stadium's big screens a number of times during the 90 minutes and, when he did, the Portuguese attracted the ire of the Belgium support.
According to the Daily Mail, the reason for this reaction owes to Mourinho's treatment of Belgium international Kevin de Bruyne who, after an impressive start to the season for Chelsea, has been cast aside by his manager.
De Bruyne made three appearances in the Premier League before the end of September, two of which were starts, but has not been used in the league since that point, but rather inconsistently in cup competitions.
Mourinho, however, was in Belgium to cast his eye over Falcao, and would have seen the Colombia international score one of the two goals that condemned the home side to their first defeat for a year.
Falcao, despite only joining Monaco in the summer, has been linked with a £60 million January transfer to Stamford Bridge.
