The 20-year-old becomes the 14th competitor from the Under 21s to test his powers of prediction for the Premier League games coming up this weekend.
Andres will be looking to over-throw leader Steven Boothman, who has been on top of the table for 11 rounds.
As usual each correct outcome of a game is worth one point and each correct score line is worth three.
Guillermo's predictions are as follows:
Chelsea 2-1 West Bromwich Albion
"The hosts will be looking to bounce back from their defeat last weekend."
Everton 2-0 Reading
"Everton will be in great spirits after their FA Cup win."
Manchester United 4-1 Norwich City
"The league leaders are in top form and will want that to continue."
Southampton 0-0 Queens Park Rangers
"Both teams will be desperate for the points but it will be a close game."
Stoke City 1-2 West Ham United
"West Ham will be determined after losing late on against Tottenham."
Sunderland 0-1 Fulham
"Fulham's confidence should be boosted after beating Stoke last weekend."
Swansea City 2-0 Newcastle United
"Their Capital One Cup success should keep them going strong."
Tottenham Hotspur 3-2 Arsenal
"Who knows what may happen in this one but it will be a very close score line."
Aston Villa 1-3 Manchester City
"City have not given up yet and will want to show that."
