West Ham United’s astonishing comeback from 2-0 down against Everton, scoring three goals in the last 12 minutes to win, is just another pointer to the growing belief within the club.

Goodison Park is not a place where the Hammers traditionally get a great deal. In fact, the club’s record against Everton as a whole isn’t great.

But past failures don’t seem to mean much under Slaven Bilic.

David Gold and Sullivan must be pinching themselves. After the awful appointment of Avram Grant and the fractious stewardship of Sam Allardyce, they have struck lucky with Bilic; a man who wasn’t first-choice for the job.

It’s seldom a manager’s Plan B goes as well as it did against Everton.

With the three centre back plan failing to deal with Aaron Lennon and Romelu Lukaku – not the first time the Belgian striker has caused the Irons problems – Bilic decided to throw on two strikers to chase the game.

Sensing Everton were weak in the air at the back, Bilic has one of the best options to exploit such a weakness and Andy Carroll (pictured) was more than up to the job.

Naturally, doubts still persist about the big Geordie – they are unlikely to be dispelled without a full season injury free – but the fact remains Carroll can cause havoc to a defence.

In fact, there is a growing suspicion Bilic may have found a way to get the best results from the famously injury-prone striker.

A roster of four or five quality forwards shouldn’t be beyond the Hammers as they prepare to move into the Olympic Stadium.

The move will enable the club to generate a bigger income and, therefore, a bigger squad.

It’s not beyond the bounds of possibility the Hammers may be able to utilise Carroll in a way that wouldn’t have been possible a couple of seasons back.

The comeback may still not have happened without the return of the dangerous Diafra Sakho and it was good to see the Senegalese striker find his touch almost immediately.

The sublime flick to lay the ball on for Dimitri Payet’s winner was worthy of the Frenchman himself.

The question now is can the Hammers make it two away wins in a row against Manchester United to reach the FA Cup semi-finals?

Most believe switching the semis to Wembley is misguided. But there is no doubt it means a day out at Wembley regardless of the result and the Claret and Blue faithful would be only too happy for the opportunity.

At any other time getting through at Old Trafford would have been a big ask. This season everyone believes.
