GB hockey's head coach Bobby Crutchley reckons there is still work to be done despite watching his side beat Argentina 5-3 to win this week's three Test series.
Surbiton's Chris Grassick bagged two goals in the victory that sealed a 2-1 Test win, which featured appearances from six Wimbledon players.
Ali Brogdon, Michael Hoare, Ian Sloan - who scored his first GB goal in the 2-1 second Test win on Wednesday - Henry Weir and Phil Roper were all involved.
Clubmate James Bailey played in the opening Test 3-2 defeat, where Surbiton's Alan Forsyth scored on his debut appearance.
Crutchley said: "We were very good in parts, but I was also frustrated with elements of the way we played.

Surbiton's Forsyth marks GB debut with a goal in defeat
"Some of our individual defending could have been better. We allowed them to win corners which they have a big threat from.
"I don’t feel we made them work hard for the corners that led to the goals, so I’m disappointed with that."
He added: "We have to be satisfied overall, however, because we scored some good goals, played some nice hockey and got a good win against a good team.
"We want to be an attacking threat and it was great to see Chris Grassick score a couple of goals.
"We’re playing him a bit further forward than he’s used to, so it’s nice to see him settling into that role."
Attention now turns to the World League Final, which starts next month.
