The Super Eagles&rsquo; Metropolitan Hotel camp in Calabar has been put under tight security as the coaching crew led by Stephen Keshi has told all visitors to stay away from the players in&nbsp; a bid to ensure maximum concentration in the camp.<br /><br />It was also gathered that the former Togo national team handler has also restricted the movement of the players as they are made to stay indoor after their training sessions so that they can remain focused on Sunday&rsquo;s game.<br />&nbsp;
