Small PHP Router

I'm building a router for my MVC Framework. How can I make it better? What am I doing right/wrong?

I have no idea about how best to handle errors. I would prefer to use exceptions - is this the right way?

=> routes.php (Register all Routes)

$route->get('/', 'HomeController@index');
$route->get('/profile/{id}', 'HomeController@show');

$route->post('/', 'HomeController@store');

=> Route.php (Router class)

class Route {

    /**
     * Store all routes.
     */
    private $routes = ['get' => [], 'post' => []];

    /**
     * Store all parameters.
     */
    private $parameters = [];

    /**
     * Requestet uri.
     */
    private $uri;

    /**
     * Store possible matched parameters from regex.
     */
    private $matches;

    /**
     * Unleash and run the router.
     */
    public function run()
    {
        $this->uri = isset($_GET['url']) ? '/' . $_GET['url'] : '/';

        foreach($this->routes[$this->requestMethod()] as $pattern => $callback) {
            list($controller, $action) = explode('@', $callback);

            $pattern = '/' . trim($pattern, '/');

            if($this->match($pattern)) {
                require '../app/controllers/' . $controller . '.php';
                $controller = new $controller();

                // remove the element for complete uri.
                array_shift($this->matches);

                // Store possible matched parameter in a flat array 
                // for call it in call_user_func_array().
                foreach($this->matches as $params => $value) {
                    $this->parameters[] = $value[0];
                }

                return call_user_func_array([$controller, $action], $this->parameters);
            }
        }
    }

    /**
     * Match the URI against the {pattern}.
     */
    private function match($pattern)
    {
        $pattern = preg_replace('#\{[^/-]+\}#', '(.+)', $pattern);

        return preg_match_all('#^' . $pattern . '$#', $this->uri, $this->matches);
    }


    /**
     * Add routes for get requests.
     */
    public function get($pattern, $callback)
    {
        $this->routes['get'][$pattern] = $callback;
    }

    /**
     * Add routes for post requests.
     */
    public function post($pattern, $callback)
    {
        $this->routes['post'][$pattern] = $callback;
    }

    /**
     * Return the routes.
     */
    public function getRoutes($requestMethod = null)
    {
        return $requestMethod ? $this->routes[$requestMethod] : $this->routes;
    }

    /**
     * 
     */
    private function requestMethod()
    {
        return strtolower($_SERVER['REQUEST_METHOD']);
    }
