Tottenham Hotspur progressed into the fifth round of the Emirates FA Cup following a 2-0 win against League Two side Newport County in their replay clash at the Wembley Stadium on Wednesday.
Spurs coach Mauricio Pochettino made 10 changes to team that played out a 2-2 draw with Liverpool at the weekend.
Newport County matched their hosts in the opening exchanges and were unlucky to go behind to a 26th minute own goal by Dan Butler.
The ball went wide to Sissoko on the right hand side and his low cross into the box took a massive deflection off left-back Butler and wrong footed goalkeeper Joe Day before going in.
Argentina winger Erik Lamela added the second goal 11 minutes from time.
Lamela slipped an effort through the legs of Day after a lovely pass from Heung Min Son.
Tottenham Hotspur will face Rochdale in the fifth round on February 18.
