Portugal began with a couple of efforts from long distance that were safely taken by goalkeeper Giles Moore before England began to exert their superiority.
Alistair Patrick-Hesleton was unfortunate not to finish with a close range effort as the Three Lions dominated, but it took until the 25th minute for England to take the lead through a fine finish from Alex Mullin to give his side the lead at the break.
The second half saw much of the same dominance from the off and a couple of early efforts were wasted to stretch the lead further. The pressure did eventually tell though as James Blackwell rose well at the back post to head home a well delivered corner midway through the half.
They finally made the game safe near the end of the game as George Fletcher scored with a diving header at the back post once again.
England have further games to come against Tunisia on Saturday and the USA on Sunday.
