Rss does not return Thumb in wordpress

Question

Guys, I’m trying to list posts from another site via RSS. Everything appears except the images Thumbs..

My result and code is this:

NOTE: I have access to the server of the files where I want to pull the posts, if anyone knows an alternative to this, please let me know... CODE BELOW:

<?php

    if (isset($_GET["xml-feed"])) {
        $strXml   = file_get_contents("http://www.euvosescrevi.com.br/feed/");
        $xml      = simplexml_load_string($strXml, "SimpleXMLElement", LIBXML_NOCDATA);
        $json     = json_encode($xml);
        $array    = json_decode($json, true);
        $arrItens = (array) isset($array["channel"]["item"]) ? $array["channel"]["item"] : "";  
        if (count($arrItens) > 0) {
    ?>

    <hr>
    <div class="blog-posts row margin-bottom-60">
        <?php
        $countItens = 0;
        foreach ($arrItens as $arr) {
            if ($countItens >= 2) break;
            $title = $arr["title"];
            $link = $arr["link"];
            $pubDate = date("d/m/Y", strtotime($arr["pubDate"]));
            $description = word_count(strip_tags($arr["description"]), 50);
            $countItens++;
        ?>

        <div class="col-md-6 col-sm-6">
            <h2><?php echo $title; ?></h2>
            <ul class="blog-info">
                <li><i class="fa fa-calendar"></i> <?php echo $pubDate; ?></li>
            </ul>
            <p><?php echo $description; ?></p>
            <p><a class="more" href="<?php echo $link; ?>" target="_blank">Leia mais <i class="fa fa-angle-right"></i></a></p>
        </div>
