The 23-year-old also spoke after the Sunderland game, in which he played the last half-hour, and is optimistic the team's return to winning ways has set them up well for a first attempt at capturing the Club World Cup.
Nine goals scored and two wins in the past two games suggest a return to the form that impressed in the early part of the season, and the way they went about beating Sunderland on Saturday was appreciated by the young left-sider, who came on for Victor Moses.
'We started the game as we needed to, being positive, and we managed to create a few chances right from the start,' Bertrand observes.
'We managed to continue that and although Sunderland applied a bit of pressure at the end, we already had the three goals by then, so it was comfortable.
'Fernando Torres managed to score two goals the other night and he managed to do it again in Saturday's game,' he adds, 'and any player who can contribute goals is always going to have a positive impact on the team.'
'Frank Lampard coming back is going to be very important because he is another who brings goals to the team.'
Turning his attention towards this week's tournament in Japan, Bertrand echoes the words of Rafael Benitez when considering the games ahead.
'We are going out there to really give a good account of ourselves,' says the 23-year-old.
'It is not often you get the chance to compete in this competition, you have win the Champions League, and hopefully we are going to go out there and do really well, keep the good results coming and bring it back to the Premier League.'
