Cliftonville were held to a 0-0 draw by Hungarian side Debrecen in Tuesday's Champions League second qualifying round first leg at Solitude.The Danske Bank Premiership hosts begin fairly brightly, with Chris Curran, Joe Gormley and Martin Donnelly bringing saves out of Nenad Novakovic.But Debrecen threatened more and more as time went on and they hit the woodwork through Ibrahim Sidibe in the 56th minute.As their opponents continued to make attempts on goal, Cliftonville offered little in response until the final 10 minutes, in which skipper Ronan Scannell and Curran were unable to convert decent opportunities.Substitute L'Imam Seydi then did likewise for the visitors in the dying seconds.
