Set selected option in dropdown

How can i set the selected option in my dropdown? I think i have to compare the city->id value with something, but i cant figure out how. Can someone help me with it?

    <select name="city" class="pl-10 text-base sm:text-sm mt-1 form-select block w-full text-gray-500 focus:bg-gray-100">
        <option value=''>{{__('Search cities...')}}</option>
        @foreach($cities as $city)
            <option value="{{ $city->id }}">{{ $city->name }}</option>               
        @endforeach 
    </select>

class SearchController
{

    public function index(Request $request)
    {


    	$deals = Deal::query();

    	if($request->get('category')) {
    		$deals->where('category_id', '=', $request->get('category'));
    	}
    			
    	if($request->get('city')) {
    		$deals->where('city_id', '=', $request->get('city'));
    	}

    	$deals = $deals->get();

        return view('search.index', compact('deals'));
    }

}
