Poor Allan was left almost needing to pay to get back into Goodison.

Such was the extent at which the Everton midfielder was made to flounder by the clever turn inside the penalty area from Diogo Jota towards the end of the 239th Merseyside derby on Wednesday.

With his opponent out of the picture, Jota took another took touch to steady himself before smashing into the room of the net from an acute angle beyond Everton goalkeeper Jordan Pickford.

In terms of the result, it mattered little with Liverpool having long beaten their neighbours into submission to claim only a second victory in their last 10 trips across Stanley Park.

But while it secured the Reds' most dominant scoreline at Goodison since 1982, the greater meaning will have been far more encouraging for Jurgen Klopp.

The clinical strike was emphatic evidence Jota is very much a man in form.

The Portuguese now has nine goals for the season with six coming in his last six starts for Liverpool.

Only team-mate Mohamed Salah and Leicester City's Jamie Vardy have scored more that the eight Jota has accrued in the Premier League this campaign.

Roberto Firmino's fitness concerns - returning late for pre-season training after Copa America duty with Brazil and subsequently twice hamstring - have contributed to Jota thus far making 11 starts in 14 Premier League games, the 5-0 romp at Watford in October the only top-flight encounter in which he has failed to appear. Most have come in a central position.

Certainly, the 24-year-old is being rewarded for last September taking on the challenge of forcing his way into the established front three of Salah, Firmino and Sadio Mane, a task in which other potential targets have been less willing to engage.

The potential £45million that could be handed to Wolverhampton Wanderers already seems money well spent, Jota's ability to play in all three forward positions as well as an appreciation of dropping deep into midfield making him a versatile and valuable purchase.

His all-round threat is borne out by the statistics. In his time in the Premier League, he has attempted 206 shots of which those with his left foot (86) are almost matched by those with his right (85).

Jota's tally of 22 goals in 47 appearances for Liverpool in all competitions have seen him score seven with his left foot, nine with his right and six with his head.

While his total of a mere three assists pales in comparison to those of his fellow forwards over the same period - Salah has 13 in 70 outings, Mane 10 in 67 and Firmino 10 in 59 - the moniker "Jota the slotter" is well deserved with none of the other leading top-flight scorers boasting a better shot conversion ratio.

The consistency of Jota is all the more important given the looming issue of how Liverpool can best cope with the loss of Salah and Mane to the Africa Cup of Nations for at least two - and possibly as many as four - Premier League matches. The Portugal international could temporarily become the talisman.

Before then, though, Jota is preparing for his latest return to Molineux this Saturday having scored the only goal in the fixture last season.

There were, of course, no supporters inside the stadium that March evening, and it will be interesting to see how the Wolves fans react to coming up against their former player for the first time since his exit.

What's certain, though, is they will have the ideal opportunity to gauge just how much Jota has progressed in the last 15 months.
