In a small bowl, combine garlic, flour, tomato paste, anchovy paste, and beef bouillon. Set aside.
Heat oil in a large skillet over medium high heat. Add roast and cook until browned on both sides, about 5 minutes per side. Add roast to a 4-6 quart slow cooker. Place skillet back on the heat.
Add flour to hot skillet. Stir constantly and cook for 1 minute to remove the raw flour taste.
Deglaze the pan with the red wine, scraping up and browned bits. Continue to cook until wine is reduced by one-third, stirring frequently. Add the tomatoes with juice, bay leaves, sage, rosemary, nutmeg, salt, and red pepper flakes. Bring mixture to a boil and cook for 3-4 minutes until mixture is thick. Pour mixture over roast in the slow cooker.
Arrange potatoes and carrots around the roast. Cover and cook until meat is tender, about 4 hours on high or 8 hours on low. Remove roast to a platter. Arrange vegetables about the roast. Strain the remaining sauce and serve alongside the roast and vegetables.
