Juan Mata has hailed Manchester United teammate Luke Shaw following his return to action in Saturday's pre-season meeting with Wigan Athletic.
The England international has been out of action since last September after suffering a double fracture of his right leg in the Champions League tie against PSV Eindhoven.
However, Shaw played 45 minutes for United in the 2-0 win over Wigan at the DW Stadium to earn particular praise from manager Jose Mourinho.
Mata has also lauded the 21-year-old for his solid performance, taking to Instagram to say: "Lots of positives from our first game, but seeing @lukeshaw23 back at it, was the best! Well done my friend."
Daley Blind, Marcos Rojo and Cameron Borthwick-Jackson all featured at left-back last season for United in Shaw's lengthy absence, but the former Southampton defender is expected to nail down the position this coming campaign.
