Former European champions Celtic and Ajax were battling for Champions League survival on Wednesday after enduring nightmare starts to their qualifying campaigns.

Celtic, with Neil Lennon taking charge of his first European tie, saw his Scottish side slump to a 3-0 defeat to Sporting Braga in Portugal in the first leg of their third qualifying round tie.

Ajax, four-time winners of Europe’s premier club tournament and coached by former Tottenham boss Martin Jol, were held 1-1 at home by PAOK Athens.
