F365 says liverpool needed the oomph of the ox
A reference to the popular football media outlet, Football365!
It seems that they're suggesting that Liverpool's performance was lacking a certain level of energy and intensity, which was provided by the introduction of Alex Oxlade-Chamberlain (aka "The Ox") to the game.
In other words, Oxlade-Chamberlain brought a much-needed injection of pace, power, and dynamism to the Liverpool attack, helping to lift the team's performance and create more scoring opportunities.
The phrase "oomph" is often used to describe a sudden burst of energy or momentum, and in this context, it's implying that Oxlade-Chamberlain's arrival on the pitch gave Liverpool the "oomph" they needed to turn the game around.
