'I think it's so exciting to be here - I think [US Soccer is] maybe the biggest challenge that we are going to [have]. We had another challenge, but this one is amazing.
'Then to help [the US] to evolve in soccer. I think to be a part of that, I think it's creating [in] us the motivation to accept that challenge.'
Pochettino added, 'If you said to me I need to pick only one sentence or one word, it's because we believe. It's [to] believe we can help... to work together, to try to achieve what the people and us all want: to win and to win good games, if not to go for big trophies.
'To have the possibility to be there competing for the World Cup or the Copa America or the big trophies that all the fans - and of course the players and us - want to be doing.'
