Graham Potter must decide whether he changes a winning team for his home Premier League debut as Albion head coach.

The former Swansea boss has been giving some guides as to why he adopted a 3-4-3 system for the Seagulls.

A likely full house will turn up for the West Ham game intrigued to see how it fares in a home match.

There will always be the chance Potter could change the plan given what he expects from the Hammers.

If as seems likely, he sticks with 3-4-3, the fact his side won 3-0 at Watford last week is no guarantee of an unchanged XI. Not with four new signings keen to start.

Fans who go to pre-season games saw the 3-4-3 in action at Birmingham and then at home to Valencia, both of which were impressively won.

Potter said: “It can be a three, it can be a five. It sometimes depends.

“Essentially you have got Shane (Duffy), Lewis (Dunk) and Dan (Burn) as a back three pushing Solly (March) and Martin Montoya on.

“It helps keep the width there.

“We want to try and build up our attacks from the back so the extra player sometimes helps.

“It also fits the overall attributes of the group in a good way.”

Potter believes Dunk has the “personality” to play as the central man in the back three.

Meanwhile March has adapted to the left-sided berth.

Potter said: “Solly is that modern day wideman who often ends up quite deep anyway so he is comfortable to do that.

“He is able to do that, he can cover the ground no problem.

“I’d say there is probably more to come from him as well.

“We are just at the start of what we are doing. We have been working together for a few weeks, that is the reality “We have to get better at everything. That’s the truth.

“But that is normal as well.

“I think after five or six weeks together you need the competition to start because that is when you get your true information.

“When that starts, you can analyse your performances in the competition phase of the year.

“But, in terms of needing to improve, there is room for everything to improve and that is the exciting thing.”

So what about selection? Potter used the same XI in those wins over Birmingham and Valencia and said Leandro Trossard was unlucky to then miss out at Watford, where Pascal Gross stepped up.

That proved to be a sound move. Gross went to the right with Jurgen Locadia going to the left, either side of Glenn Murray.

Gross was involved in the first goal and had the nous to work spaces for Montoya to attack outside him.

But Trossard delighted the Amex against Valencia. And Neal Maupay scored soon after going as sub against Watford.

At some stage, injury, suspension, poor form or fatigue will force changes.

But will Potter see something that catches his eye about West Ham and make an alteration or two while he is ahead of the game?

He said: “That’s the thing I will ponder over.

“We have a group that is ready to help the team, that’s the good thing.

“We have options from players.

“The guys that started (at Watford) did well, the guys who came on did well. That is what you want.

“Even the guys who didn’t get on the pitch have trained well this week.

“The group is in a good place and it is nice to see.”

Potter is aware the challenge will not be easy, despite West Ham losing 5-0 at home to Manchester City on day one.

He said: “Their front four especially are really technically gifted.

“They are a top-ten team who have continued to try and improve, who have invested well.”

They have a really experienced, knowledgeable coach, and very good individual players and an organised team structure.
