Pep Guardiola was not the only tetchy Bayern Munich man during their 1-1 draw at Manchester United on Tuesday night, as midfielder Toni Kroos appeared to contest his second-half substitution with his coach.
Before Guardiola disputed Bastian Schweinsteiger's sending off, Kroos, a United transfer target, seemed to object to his withdrawal for Mario Götze in the 74th minute with Guardiola.
Kroos wanted clarification from Guardiola as to why he was substituted
The German midfielder scored Bayern's opener at Arsenal in February
The two became involved in an animated conversation for a few seconds before Kroos eventually made his way to the Bayern bench.
Kroos appeared to object to his withdrawal for Mario Götze
Although the exchange was hardly heated, it was another negative reaction from Kroos, out of contract in 2015, following his response to being substituted at Stuttgart earlier this season.
Kroos is out of contract in 2015 and is wanted by United
Kroos angrily tossed his gloves to the floor and refused to acknowledge a member of Bayern's staff as he walked to the bench, before Thiago Alcântara scored a stunning late winner.
Kroos could start for Germany at this summer's World Cup finals
Kroos was one of Bayern's better players on a night they struggled to break down a depleted United defence.
United 1-1 Bayern
