Style of play
Gaitán began playing as a midfielder, sometimes leaning to the left. After moving to Benfica he assumed a more advanced role, where he seemed more comfortable.
A left-footer who is also able to play on the right, with good dribbling skills and close control, Gaitán's main asset is ball distribution as he is able to cross from either flank, and while on the right he possesses the vision to pick holes when cutting inside.[46][47]
