Everton, whose Scotland right-back, Nathan Patterson, is drawing strong interest from clubs in Germany, Italy and Spain, are preparing to firm up their interest in Celtic 27-year-old Alistair Johnston. Mika Baur has informed Paderborn of his desire to join Celtic this summer after the 22-year-old midfielder agreed personal terms with the Scottish champions. Mika Baur missed Paderborn's friendly with Southampon on Wednesday, but the German club's claim that the Celtic target was ill is not accurate.
