US sack former Matildas coach
The sacking of the former Matildas coach just 15 months after taking up the post has surprised US football media.
It follows reports that players within the Matildas squad have lost confidence in Dutch coach Hesterine de Reus who replaced Sermanni after eight years in the job.
The 59-year-old Scot took over the US team in January last year and led the women’s team to a record 13 wins (3 losses) season.
In an official statement US Soccer President Sunil Gulati: "We want to thank Tom for his service over the past year and a half, but we felt that we needed to go in a different direction at this time.
"We will begin looking for a new coach immediately to guide our women's national team toward qualifying for the 2015 FIFA women's World Cup."
Director of development for US Soccer Jill Ellis will serve as the interim coach.
Sermanni said: "I'm disappointed that things didn't work out, but I'd like to thank US Soccer for the opportunity to have coached this team and also the staff and players for all their hard work.
Despite Sermanni's success with the team there was disappointment over the side's seventh-placed finished in last month’s Algarve Cup - a global invitational tournament hosted in Portugal.
