Ronald Koeman's side, which thrashed Canada 4-0 in its penultimate warm-up game, was comfortable winner again six days out from its opening Group D game against Poland.

The Oranje went ahead after 23 minutes as Denzel Dumfries headed Joey Veerman's chipped pass across goal for Simons to convert, then doubled their lead four minutes into the second half.

Nathan Ake's flick-on from a corner found Van Dijk, who beat Iceland goalkeeper Hakon Valdimarsson to head the loose ball home.

Three days on from its memorable win over England at Wembley, Iceland went close to halving the arrears when Stefan Thordarson's 30-yard drive was tipped onto the post by Bart Verbruggen, but it fell further behind when Memphis Depay played Malen in to finish into the bottom-right corner after 73 minutes.

Netherlands got a fourth in stoppage time as substitute Wout Weghorst tapped home from close range, a VAR review confirming the goal after Malen was initially flagged offside before crossing for the former Manchester United loanee.

Lacking a top-class number nine, Netherlands will likely have to share the goals around if it wishes to go deep at the Euros. Fortunately for Koeman, he can call on one of Europe's very best attacking full-backs in Dumfries.

The Inter man has been involved in 19 goals for the Netherlands overall (six goals, 13 assists), edging ahead of Daley Blind (18) for the most goal contributions by any Oranje defender.
