Mauricio Pochettino admits stern words have been needed to convince Vincent Janssen he can be a success at Tottenham.
Striker Janssen is back in the spotlight with Harry Kane nursing an ankle injury, but the Dutchman faces a fight to rescue a miserable debut season at White Hart Lane.
His goal against Millwall last weekend was Janssen's first from open play since joining for £17.5million from AZ Alkmaar eight months ago and he failed to take his chance when Kane was out for seven weeks in the autumn.
Ten appearances in that period yielded only three goals for Janssen - all from the penalty spot - as Tottenham went five games without scoring from open play and six without a victory.
