Scott, who was named captain by manager Phil Neville, scored with a second half header to secure the win, after former blue Nikita Parris had opened the scoring.
But it was an unconvincing performance for the Lionesses, who struggled at times to retain possession, allowing Denmark to have a couple of opportunities of their own.
New City signing Ellen White put a shot wide after being put through by Scott, and Denmark had a goal disallowed as the ball bounced onto Signe Bruun’s shoulder and in, only for the referee to disallow for handball.
Nerves were eased just before half time, when Parris fired home from the edge of the area to put England ahead.
Scott made it 2-0 on 58 minutes. Georgia Stanway’s breakaway run released Beth Mead, whose cross was met brilliantly by Scott, who powered home her header to make the game safe. England left the likes of Steph Houghton and Lucy Bronze on the bench, while former blue Toni Duggan was not named in the match day squad, but England have shown they have the strength to still grind out a win.
The Lionesses face New Zealand next Saturday in their final match before the World Cup, which kicks off in France on 7th June, with England’s first Group D match coming against Scotland two days later.
