Celtic chief executive Peter Lawwell has vowed to "enhance" Gordon Strachan's squad for next season, with one eye on a successful Champions League campaign. The Bhoys were embarassed last season in European football's blue-riband event and Lawwell is anxious to build on a squad, with uncertainty surrounding the futures of several key players. "We will continue to support Gordon's plans and will work hard to make sure that the quality within our squad is maintained and enhanced for the challenges ahead," promised Lawwell
