Gunners scouts have given glowing reports after watching the 25-year-old in action.- Tuttosport says Tottenham have joined the race for Juventus winger Douglas Costa. Costa has not featured for the Serie A champions since early February, and a fee of £60m should be enough to secure the 28-year-old's signature.
