Van Gaal explains Darmian sub: Did you see Tadic in the second half?

Manchester United manager Louis van Gaal was delighted with the outcome of his half-time tactical decision to close down Southampton playmaker Dusan Tadic, claiming the player was invisible after the break.

The Red Devils boss explained how he was forced to replace first-choice right-back Matteo Darmian with Antonio Valencia due to Tadic's first half prominence.

The Dutch boss was thrilled with his team's marking of the Serbian winger following the interval and revealed why he felt he made the correct decision in the 3-2 victory.

"Because he gave too much space to Tadic in my opinion, so that's why I brought on Valencia," Van Gaal told reporters.

"I didn't see Tadic in the second half, did you?"

Goals from Anthony Martial and a Juan Mata strike earned United their fourth Premier League win of the season, with their latest three points lifting themselves up to second in the table.
