Tomiyasu is on track to play his first game since January on Saturday, manager Mikel Arteta said on Friday as his team prepares to host Premier League top-four rivals Manchester United. Tomiyasu, 23, joined Arsenal from Bologna in August and made 17 appearances in all competitions before being sidelined with a calf injury. Arsenal boosted their chances of qualifying for the Champions League for the first time since 2015-16 after Wednesday's win at Chelsea left them in fifth place with 57 points, three ahead of sixth-placed United.
