Products update; admin pannel

hi friends, I have a problem with the update method of my administration panel;

Instead of updating the data of the current products, this what it does is create new ones and it will not let me delete them later (neither the updated ones nor the previous ones).

It is as if he created clones that can not be erased, but with the variation of only one. I do not know if I can explain ...

productscontroller

 public function update(SaveProductRequest $request, Products $products)
    {
    $products->fill($request->all());
    $products->slug = str_slug($request->get('name'));
    $products->visible = $request->has('visible') ? 1 : 0;
    
    $updated = $products->save();
    
    $message = $updated ? 'Producto actualizado correctamente!' : 'El Producto NO pudo actualizarse!';
    
    return redirect()->route('products.index')->with('message', $message);
   }

public function destroy(Products $products)
{
    $deleted = $products->delete();
    
    $message = $deleted ? 'Producto eliminado correctamente!' : 'El producto NO pudo eliminarse!';
    
    return redirect()->route('admin.products.index')->with('message', $message);
}

web.php

Route::post('products/{products}', [
'as' => 'admin.products.update',
'uses' => 'ProductController@update'
 ]);

Route::delete('products/destroy/{products}', [
'as' => 'admin.products.destroy',
'uses' => 'ProductController@destroy'
]);

form

    {!! Form::model($products, array('route' => array('products.update', $products->slug))) !!}
