Another weekend, another Liverpool victory.

This time, Tottenham Hotspur were the victims. This was not the most convincing of victories for the Reds - Spurs actually had more shots come the end of the match - but that doesn't seem to be too much of an issue these days. In the end, the 1-0 scoreline was enough to pick up all three points.

Call yourself a Liverpool expert? How much did each of these big-money January signings cost?

Roberto Firmino scored the only goal of the match, with a well-taken strike after 37 minutes. There has been speculation about the Brazil international potentially leaving, with Real Madrid said to be interested as they plan to eventually replace Karim Benzema (fichajes.net via calciomercato.com). With this display, the former Hoffenheim man will have added a few million to any potential price tag.

This display showcased the 28-year-old at his very best. The striker played a huge role in his team's dominating performance. He had 52 touches of the ball, which for a striker is rather impressive - Firmino actually has the most touches amongst all strikers in the Premier League this term, averaging 44 per match - and he landed 87% of the passes he attempted.

Often applauded for his teamwork and ability to link up with his teammates, he showed of those skills once again at the Tottenham Stadium. His four key passes were matched only by Christian Eriksen, who as an attacking midfielder is expected to be far more prevalent in that area. Not only that, he also showed his worth defensively, making one tackle.

This campaign, there have been questions about his form - from some of the club's fans no less - about whether he is replaceable in this Liverpool team. Yet just when you begin to wonder whether the Anfield outfit could do better, he throws up a performance like this. We may need reminding every now and again, but what he is able to provide to this team is priceless, and that is why Jurgen Klopp has persevered with him despite his lack of goals - he had just four in all competitions going in to December. Now that the 44-time Brazil international is once again beginning to find the back of the net more regularly - he has five goals in his last 12 - he has repaid that faith in him from his manager.

Elsewhere, this Liverpool transfer target would be an upgrade on Georginio Wijnaldum...
