The midfielder was a shock inclusion in New Zealand's 23-man World Cup squad and now Phoenix CEO Tony Pignata has revealed the 23 year old was training with the club.

"We'll build the squad accordingly to what's required. But if he does have a great World Cup, then definitely, we'll look at him. He's on the radar," he told Radio Sport.

Clapham currently applies his trade with Canterbury United in the New Zealand Football Championship.

The uncapped Under-20 international is the bolter in the All Whites squad for South Africa, where they will face Italy, Paraguay and Slovakia.

In other news, former Melbourne Victory youth player Mathew Theodore is set for a one-week trial with Gold Coast United.

The 20-year-old has been in solid form with struggling Victorian Premier League outfit Altona Magic but will miss this weekend's game against Oakleigh as he attempts to break back into the A-League.
