Manchester United manager Louis van Gaal has confirmed Ander Herrera and Phil Jones will miss the Premier League trip to Leicester City on 28 November due to injuries. The Dutch boss refused to set a deadline on the return of the United duo but claims one of them could be back within two weeks.

The Premier League giants visit the leaders following a disappointing draw in the Champions League tie against PSV Eindhoven on 25 November. United will then host West Ham United on 5 December before a game against Wolfsburg on 8 December to determine whether they progress to the last 16 of the European competition.

Van Gaal has suggested both Herrera and Jones will struggle to feature for the crucial Champions League fixture. The duo missed the midweek draw against PSV after picking up respective hamstring and ankle problems during the Premier League win over Watford.

Asked by MUTV about a date for their returns, he said: "I cannot say that also because these kind of injuries you cannot predict. I don't think it is weeks, but I think within two weeks one of the two can come back. But I don't know, you can never predict that, because injuries are unpredictable."

The manager is also without Michael Carrick and long-term absentees Luke Shaw and Antonio Valencia. When asked if any of the players picked up injuries during the game against PSV, he responded: "It's too early to say something about that but it was a very intense game."

Meanwhile, speaking in the press conference ahead of the visit to the leaders, the Dutch boss warned about the danger of Jamie Vardy, after the in-form striker struck when Leicester beat United 5-3 in the 2014-15 season.

"He was already last season a very nasty player for us," Van Gaal said. "I remember Vardy in that game, so I don't want to remember that game especially, because of the result but also the way we lost wasn't good."

"Vardy scored, won a penalty, and now he is scoring 10 games in a row. I only know Dennis Bergkamp, as a player with me, who did the same with Ajax. It's not so easy to do that. That game [against Leicester], I said also in the press conference after, we lost because the referee gave a penalty, against Rafael, I remember that very well. In my opinion, he [the ref] changed the match, but of course it was still 3-2 then, so you cannot blame the ref you have to blame yourself, but it was the return of Leicester in that game."
