Nobody can say we'll short of left wingers now, and he's got Stan in his name!
The 19-year-old can play on either flank and up front and is an England under 19 international.
The set piece specialist, who has been at Upton Park since he was 11, has also been given clearance to play in Saturday's FA Cup clash with Luton Town.
The official site tells us he's got a mean shot, I presume we'll get a chance to judge at the weekend.
Some comments from a Hamster website regarding young Junior whose a Brazilian in disguise it seems!
There was a big bit in a recent promise highlighting the promise of Marek Stech… the next Petr Cech. Freddie Sears and Junior Stanislas score for fun for the U18's and quite often for the reserves last season.
I have played with Junior Stanislas since secondary school and he is A BRILLIANT player and I have no doubts he will make it...he is a mixture between Ronaldo and Scholes…he is quick, good finisher, and has a great vision for a pass! I truly belive he will be in the West Ham squad and maybe first 16 next season!
See the u19's play a few times last season, the first thing that's evident - Junior Stanislas is going to be an amazing player. One the very best WHU have ever produced. Electric acceleration and speed, with clinical and composed finishing. Brilliant 1on1 with a keeper, just curls the ball into the net like Henry. He can blast it too. Athletically built like a sprinter, with incredibly quick feet - and likes to do step overs, lots and lots step overs, which are very, very fast - like Nani, Ronaldo, Robinho. He plays like a top Brazilian. This kid is dynamite! Gonna be World Class!!
(Blimey, if that's true we'll all in for a treat over the next few weeks!)
