[OpenLayers-Users] WFS layer over Google Map layer projection problem

Hi,
I'm using geoserver to serve wfs features that uses EPSG:4326 projection. I
want to display them over a GoogleMap layer (EPSG:900913projection). I uses
Mercator Options as is mentionned in many topics but I still have
superposition problems. It's seems that features coordinates are treated as
mercator coordinates rather than degrees.
There is my code :

var mercatorOptions = {
        controls: [],
        projection: new OpenLayers.Projection("EPSG:900913"),
        displayProjection: new OpenLayers.Projection("EPSG:4326"),
        units: "m",
        numZoomLevels: 18,
        maxResolution: 156543.0339,
        maxExtent: new OpenLayers.Bounds(-20037508, -20037508,20037508,
20037508.34)
};
map = new OpenLayers.Map( 'map',mercatorOptions);
var gmap = new OpenLayers.Layer.Google( "Google" , {"type": G_NORMAL_MAP,
"maxZoomLevel":18,"sphericalMercator": true} );
map.addLayer(gmap);
wfsLayer = new OpenLayers.Layer.WFS( "WFS layer",
        "/geoserver/ows",
        { typename: 'topp:roads } );
map.addLayer(wfsLayer);
