Through his official Twitter account, the Australian Davis Cup captain Lleyton Hewitt criticized the International Tennis Federation once again for trying to change the Davis Cup format, by partnering with soccer star Gerard Pique's company Kosmos.

'Another weekend of @DavisCup tennis showcasing all the elite talent the tennis world has to offer,' Hewitt tweeted. '@ITF_Tennis have their head in the sand. Current stars and future greats representing their countries.

#Tradition Over Money. #Vote No.' The last hashtag was Hewitt's reference to the proposal being voted by the ITF members in the Annual General Meeting in August. Meanwhile, in the tournament, Australia will be playing the World Group Play-off after losing the first round to Germany in the home tie in Brisbane.
