Molby was pleased with the Reds going forward but also praised the defence for their efforts.
There is also the factor that Lovren was playing on the right side of the defence rather than the left, making his role a little more unfamiliar.
But Molby was full of praise for the back four in his Liverpool Echo column as the Reds recorded their first clean sheet of the season.
He said: "Javier Manquillo, Dejan Lovren and Alberto Moreno are all brand new players, while Mamadou Sakho is half-a-new player, but they effectively restricted a Tottenham team which had been free scoring in its first few games to just a couple of early chances.
"The full-backs pushed on well in the midfield diamond formation that Brendan used and it was a hugely encouraging display."
Some will say the side that played last week will deserve a chance to perform after the international break as well. The Reds have invested heavily in defensive reinforcements this summer, and the back line against Spurs seemed to work as well if not better than in the other two games against Southampton and Manchester City so far.
There were a couple of hairy moments, but they an be eradicated with more time playing together.
Molby also praised the side going forward as the Reds returned to a diamond formation which made them so formidable going forward last season, and allowed them to accommodate new signing Mario Balotelli at the spearhead of the attack.
"It bore all the hallmarks of what we saw last season – the energy, the tempo, the movement, getting key players involved in the game – and it filled me with enormous optimism for the rest of the season.
"We may or may not go as close as we did last season to the title, but you can safely say that we are going to be royally entertained along the way once again."
