Davy Propper has unlocked his potential by moving to the Premier League.

That was one verdict coming out of the Netherlands as Albion’s 13 internationals at senior and under-21 level headed back to club duties.

And the Dutch, especially those in Eindhoven, can see the irony of Propper, a £10 million summer signing by the Seagulls, taking centre stage for Ronald Koeman as the men in orange beat the European champions.

Propper held the centre of midfield as his nation saw off Portugal 3-0 in a friendly in Geneva on Monday.

They were three up at the break and weathered an improved second-half showing from the Portuguese.

Propper played a nice pass in the build-up to Memphis Depay’s early opener.

Then he strode around the centre ground, playing short and simple passes or offering a protective shield to his centre-backs.

Koeman offered his midfielder high praise as the Dutch improved hugely on their performance against England on Friday.

And it was the newspaper Algemeen Dabglad which picked up his improvement since coming to the Amex. They wrote of Propper: “He was perhaps the best man on the field, always free, pure in his passing and supporting the other two midfielders, Van de Beek and Wijnaldum.

“At PSV they often said: Davy does not realise half how big his possibilities are, so modest, maybe a little too much.

“But in England he seems to have been brought to life.

“The Brighton marathon man has an excellent debut season and only missed 15 minutes in the Premier League.”

The website soccernews.nl also highlighted the player’s development since arriving in England.

They wrote: “Davy Propper was always a valued force at the Eredivisie top club PSV, but he did not shine every week.

“At Brighton and Hove Albion, however, the midfielder shows that his ceiling is a bit higher.”

It fell to a website covering PSV’s fortunes to spot the most stinging irony.

Psvinside.nl pointed out: “The remarkable thing about Davy Propper is that the current national coach was able to spend twice as much on transfer money to competitor Davy Klaassen.

“Everton, on the advice of Koeman, paid the ridiculous and astronomical amount of 28 million euros for the over-rated and physically inadequate Klaassen.”

Propper will not be going to this summer’s World Cup but he seized the chance to play well just as a new head coach settles in.

Tomer Hemed will be hoping he has done likewise after scoring for Israel against Romania.

His neat flick over the goalkeeper’s dive was part of an all-round display for which he earned plenty of praise.

For Hemed, Beram Kayal and Israel, it is now all about making a fresh start with a new boss after a dismal World Cup qualifying campaign.

Hemed said: “The second half against Romania was much better than the first as it took us time to play together.

“We looked okay after not having had much time to prepare.

“At the end of the day we will have a full-time head coach before the next match.

“Each one knows what is expected of us.”

Shane Duffy added to his caps in a three-man Irish defence in Turkey on Friday during an international break in which six members of the current Seagulls squad have made senior appearances.

Mathew Ryan and Jose Izquierdo are the others while on-loan duo Jamie Murphy and Oliver Norwood take the senior tally up to eight.

Murphy made his senior Scotland debut in the defeat to Costa Rica after making quite an impression at Rangers in a loan stint which is likely to become more permanent in the summer.

Murphy said: “I feel like I’ve been capable of playing for the national team for a couple of years.

“I’ve just never had the opportunity to play every week at club level in the last year or so.

“It’s great to come up to Rangers, play every week in a successful side and show what I can do.”

As expected, Ryan did not get off the bench on Tuesday as Australia played Colombia while, for the South Americans, Izquierdo went on after 75 minutes in place of Carlos Bacca.

Izquierdo will not lack extra motivation over the remaining weeks of the Premier League season with selection for Russia within his grasp but by no means a certainty.

Albion’s five under-21 internationals doing their bit over the last week included Norwegian forward Henrik Bjordal, who scored against Italy when his intended cross missed everybody and bounced inside the far post, Bjordal, part of Simon Rusk’s flying Albion under-23 side, had a bit of a laugh about that one.

Stefan Ljubicic, the Icelandic target man on loan at Bognor, scored against the Republic of Ireland and was booked against Northern Ireland when he fouled Ben Hall, the Albion centre-back currently on loan at Notts County.

Mathias Normann, who is on loan at Molde, and Alex Mateju also headed off for under-21 duty with Norway and the Czech Republic respectively.

At younger age groups, Albion’s strong Irish connection was continued when Aaron Connolly and Rian Sullivan played for the under-19s.
