Not only did he have to patch up a spat with younger brother Ralf, he phoned teammate Rubens Barrichello on Monday afternoon to thrash out yet another track incident.
Brazil's Barrichello - like Ralf - hit out at Schumacher after the race, this time for making a last lap pass on the tunnel exit.

"'Michael rang me to wish me happy birthday and I now consider the matter is closed."
Schumacher, 36, re-tempted Barrichello's ire on Thursday, though, by calling him 'a little bit temperamental.
"I mean," Schumacher started, "it's racing, quite often you are tired at the end, emotional.
"He's pretty relaxed now."
