Luis Suarez cut the shape of a frustrated figure as he watched Arsenal - the team he wanted to join in the summer - dominated his Liverpool side on Saturday.
In a confident display, Arsenal's class shone brightly. Every area of the team seemed strong. The centre-backs were solid, the midfield was creative and the attack was clinical.
At the same time, Liverpool looked more reliant on their new striker partnership than ever. Suarez and Daniel Sturridge have been impressive this season but feeding them the ball and watching them do the rest won't work every time.
Suarez was a class above his team mates and is probably the only player who would make the starting line-up in the opposing Gunners team.
Arsenal bullied Liverpool off the pitch, laughing at their prospective title credentials. Now they need to compound that dominance and force Liverpool to sell their best player to them in January.
Arsene Wenger has the funds at his disposal to launch another record-breaking bid and knows Suarez, who stated his desire to leave Liverpool only months ago, will still be keen to leave the team he is carrying.
Morality doesn't even come in to it. Wenger can't worry about hurting Liverpool's feelings by trying to unsettle the Uruguayan once again.
Suarez has shown that Arsenal's infamous £40m plus £1 bid was rejected with good reason - he is worth more than that.
He has the quality to pick up a stuttering team and carry them to victory. He inspires his Liverpool team mates in to action; he inspires the crowd to sing - he is worth at least £50m in today's market and Arsenal must offer at least that to test Liverpool's mettle.
Arsenal want to be winners and to do that they need to start bullying teams on and off the field. They've displayed their dominance over Liverpool and shown Suarez that he has a better chance of winning trophies at the Emirates. He'll no doubt still love to join Arsenal, he only needs the incentive to kick up a real fuss.
In the form of a £50m+ bid, the Uruguayan international will have that incentive. Knowing how much Wenger wants him, he may be inspired to hand in that all-important official transfer request.
The chances of Arsenal landing Suarez remain slim, but Wenger mustn't sit back when he knows one of the world's brightest talents wants to join his strengthening side.
If the bid fails, so what? Then Arsenal still have £50m to reinvest elsewhere.
But Arsenal must not stagnate like many of their opponents are doing. They must take advantage of their newfound dominance and go for the jugular. Signing Suarez will set them head and shoulders above the rest.
