Shim Mheuka has shrugged off his European omission to focus on becoming a domestic star for Celtic. The 18-year-old striker has been left out of Celtic's Europa League squad along with fellow Chelsea loanee Landon Emenalo and newly-signed Dutch midfielder Joel van den Berg. England youth international Mheuka has made two Celtic appearances off the bench and was denied a first goal for the club when his strike against St Mirren last weekend was disallowed for offside.
