Ajax's calamitous season worsened when the Amsterdam club suspended new CEO Alex Kroes on Tuesday and said it intends to fire him on suspicion of insider trading in the club's shares. Kroes, who started at Ajax only last month as a permanent replacement for Edwin van der Sar, could not immediately be reached for comment. A successful sports administrator, Kroes was seen as a key to bringing the struggling four-time European champion back to the top of Dutch and European soccer after a dismal start to the season when Ajax fell into the Eredivisie relegation zone and fired coach Maurice Steijn.
