Manchester United's under-pressure manager Erik ten Hag has explained why he substituted Marcus Rashford at half-time in their 3-3 draw with Porto on Thursday.

The Red Devils squandered a 2-0 lead away at Porto in the UEFA Europa League before needing a late goal from Harry Maguire to win a point from the tie.
United opened the scoring through Rashford early on as the Englishman looked a threat down the left-hand side, but his game ended after 45 minutes.
Ten Hag replaced the winger with Alejandro Garnacho after the break, perhaps surprisingly, although the 54-year-old suggested it was due to Rashford's lack of defensive work.
"I have to watch it back and over the left side, definitely we didn't defend well tonight," he said, according to First Post.
"Marcus also played a part in this but as I say it had to do with Garnacho coming on – and nothing against Rashford.
"We have to rotate. We have a tough game on Sunday (at Villa Park) and we need players fresh."
The Red Devils will go up against Aston Villa away in the Premier League on the weekend in what is a must-win game for Ten Hag.
