"This was a good win for us, and especially to get a second win this weekend is a great boost for us," Johnson said. "These games are a great preparation, Portugal are a well drilled side and it's a nice warm-up for our next game against USA. "
Standard Life GB head coach Chris Finch afterwards praised the effort of the bench as all Great Britain players got on the scoresheet.
"Kyle Johnson shot the ball very well and has been a great find overall for us, but all the players we have are great finds and they all contributed well in this game," Finch commented.
Finch added: "Overall though tonight was a great performance, yesterday was rusty so it was much improved today, especially our second half showing, lots of things to be happy about and everyone was really focused and played really sharp."
