He added: "Straight after the win at Wigan the lunch was mentioned by the players so we will put that in place soon. It's another one that's cost me a bit of dough.
"What we have shown in the big games so far this season is that we can compete.
"If we don't make individual errors in these games, we have got every chance of beating any team in this league.
"We know that our home form is getting better and better all the time and we will be a different proposition on Sunday against a top team than maybe what we were at the beginning of the season.
"Our cohesion, spirit and quality is getting better all the time. It will be a really tough game because Tottenham are in good form but I'm looking forward to seeing the development of the group. We have to keep this momentum going in order to grow as a team."
A recurring theme for the Reds this season has been the importance of grabbing the first goal, although Rodgers plans to work on his team's patience too.
"Throughout the Premier League this season, the first goal has been important for many teams," the boss said.
"Scoring in that opening 20 minutes really settles you. It also means your opponent has got to come out and play and that opens up space for you.
"We're still finding our patience in games. That's something that's important for us going forward.
"With teams that regularly win things, it doesn't matter if they are 2-0 down at half-time. They have the calmness and patience to come back and win games. That comes with experience."
