Manchester City could have Kevin de Bruyne and Sergio Aguero available as they look to win the Carabao Cup for a record-equalling eighth time.
Tottenham's last trophy was the League Cup in 2008 and striker Harry Kane's chances of playing at Wembley are being monitored "hour by hour".
Kane missed the midweek win over Southampton with an ankle injury.
'We want to win this competition'
City have the first leg of the Champions League semi-final with Paris St-Germain looming next week but Guardiola was keen to stress a fourth straight League Cup win is important to him.
