Tottenham played out a 1-1 draw with Arsenal at the Emirates Stadium in the North London derby just before the international break.
Spurs returned to winning ways in the Premier League this evening with a comprehensive victory over West Ham at White Hart Lane.
Former Tottenham midfielder Jenas was following the game, and he has pointed out a difference in their performances.
"That was really good play, by Spurs,” the former Newcastle United star said on BBC Radio 5 live just after Tottenham scored their second goal on 33 minutes.
“They’re showing more of the killer instinct they didn't have at the Emirates against Arsenal a few weeks ago.
"They're sensing they can finish this game off, that they should go for the jugular before West Ham can make changes at half-time.”
Tottenham were superb throughout the match, especially in the first 45 minutes, and took their chances.
Against Arsenal earlier this month, Mauricio Pochettino’s side failed to take the chances they created and allowed the Gunners to score the equaliser in the second half.
The win against West Ham means that Tottenham remain in the hunt for a top-four finish in the Premier League this season, and perhaps even the title.
