Manchester United fans have been used to attacking football for almost 3 decades now. Hence, they are not taking the defensive tactics of manager Louis van Gaal easily.
The Dutchman has come under criticism almost since he came as a replacement for David Moyes. The criticism shows no signs of dying down even after the latest win over CSKA Moscow in the Champions League. The 1-0 victory keeps United in the hunt for a last 16 spot, which is very important especially after the opening group game defeat against PSV Eindhoven. In order to achieve a victory with a clean sheet, United opted for defensive tactics.
