It is never too late to make an impression – or play your part in a win.

Graham Potter will remind his nine substitutes of that as they take their scattered seats in the West Lower tomorrow.

If he thinks he needs to, of course.

He might think he does not have to hammer home the point too much.

Players have already seen the need to be ready right up until Potter makes his fifth permitted change under the current restart rules.

The Albion boss has made a full house of subs in this final chapter of the season – 20 in four games.

Thirteen different players have gone on as sub in the last four games, led by Solly March with three outings off the bench.

Shane Duffy equalled Alexis Mac Allister as the latest substitution in that time for the Seagulls when he entered in the fourth minute of injury time at Norwich.

The thinking behind that was fairly clear.

He replaced Tariq Lamptey with Adam Webster moving across to right-back in a super-sized defensive quintet.

The clean sheet and win was subsequently secured.

Mac Allister played a part off the bench in his three minutes against Arsenal as his pass led to the winning goal.

Potter has been pleased with the contribution of all players in his squad.

He revealed: “We have made a point of saying, ‘Look we are going to need everybody here’.

“It’s not just the starting XI. It’s the people who come on, it’s the guys that don’t get on.

“It’s about how they communicate their disappointment because it’s normal that players want to play.

“How they act with each other has been really good.

“Also, the way the matches are, Alexis Mac Allister came on against Arsenal for maybe a minute, two minutes but he contributes the key pass.

“Shane Duffy comes on at the end of the Norwich game and he has to defend two actions in his box.

“So the importance of the professionalism and the character of people coming on at the end of the game are so important for us.

“We want to get to a stage, and we are working towards it, where every day at training it is about how we are with each other, how supportive we are.

“We understand players want to play, of course.

“That disappointment is normal but how you channel it and how you act as a group is so important for us as a club.”

Mac Allister, Duffy, Dale Stephens, Leandro Trossard and Bernardo have each gone on twice in the restart matches.

There has been one substitute appearance apiece for Martin Montoya, Aaron Connolly, Davy Propper, Glenn Murray, Neal Maupay, Aaron Mooy and Pascal Gross.

Albion made four changes before the hour mark at Leicester, of which one was injury-enforced.

By contrast, Potter waited 72 minutes before going to his bench at Norwich.

Potter is not particularly set on the option for five changes remaining into next season, despite his effective use of the system.

The same goes for the water break, which was introduced for these summer fixtures.

But he will use those mid-half intervals to get brief messages across while he can.

Albion dropped Maupay into a deeper area during the drinks interval in Saturday’s first half and it helped them score the only goal of the Carrow Road contest.

Potter said: “I wouldn’t say it comes into my (tactical) thinking but it’s a break in the game.

“It has taken away, I think, from what the Premier League is.

“We knew why it was there.

“It was a part of getting everything restarted and it was a part of playing the games.

“I understand why it’s there but you know it has its disadvantages as well, especially if the weather isn’t really, really warm.

“It seems a bit strange to have drinks breaks then and you’d like some common sense to be used in some instances.

“But, if the rationale is you want to give breaks to protect against injuries, then I understand.”
