After suffering a big loss away to Legia Warsaw in the UEFA Champions League third qualifying round mid - week, Glasgow Celtic had hoped to make amends in the tuneup game with Tottenham Hotspur held on Saturday.<br /><br />But the Scottish champions were further exposed at the back as they suffered a heavier defeat, this time embarrassingly losing 1 - 6 to their British rivals. <br /><br />Six different players - Kane, Soldado , Holtby , Lamela , Eriksen and&nbsp; Adebayor - were on the score-sheet for the Londoners while Lindsay&rsquo;s goal just before half time turned out to be only a consolation.<br /><br />For the second straight game, Efe Ambrose&rsquo;s lack of judgement was exposed after he was dismissed in the 90th minute.<br /><br />Recall that the Nigeria international also took the walk of shame in the 1 - 4 loss to Polish champions Legia Warsaw three days ago.<br /><br />
