"I had a few options to choose from and I thought, 'if I get myself to a big club and I am playing regularly, that gets my name out there' - and obviously my name did get out there.
"I knew that was the opportunity I had to take so that I could get to this stage now.
"We are not fearing anyone.
"We are all talented players and if individually we can do our best, then together we are so strong."
