Carlos de los Cobos has been shown the door in Chicago after leading the Fire to an overall 1-4-6 record this season.

The Fire, who have gone winless in their past nine matches, sit second-bottom in the Eastern Conference with nine points from 11 games.

Meanwhile, Teitur Thordarson has paid the price for Vancouver's poor start to life in the MLS, sacked at the rookie club following a winless streak dating back to their first-ever match in the top-flight.

The Whitecaps have not won since announcing their arrival in the MLS with a 4-2 defeat of Toronto FC in March.

They prop up the Western Conference table with nine points from 12 matches.

Director of Soccer Operations Tom Soehn will take over in Vancouver on an interim basis, while technical director and former Fire player Frank Klopas has been handed the reins in Chicago.
