The wait for Louis van Gaal to be officially revealed as the new Manchester United manager continues. It is now believed that the announcement about the current Netherlands boss may not now happen until next week.

According to The Guardian, United will wait until everything is signed and sealed before making a renewed bid for one of their leading transfer targets, Luke Shaw. The recently deposed Premier League champions had a £27 million offer rejected for the young England left-back earlier this week, but are reportedly set to return with one of £30 million.

Southampton have previously insisted that they do not want to lose any of their leading players, but such an offer could well prove too hard to turn down. The futures of Shaw and fellow sought-after star Adam Lallana could also be tied to that of manager Mauricio Pochettino, who is thought to have been lined up to take over at Tottenham. Yet, were Southampton to reject the latest bid, United may be loathed to go any higher, with the club said to have also agreed to pay the 18-year-old England international £100,000 a week.

Van Gaal’s targets are likely to be pursued thick and fast when he is appointed, with the Manchester club eager to avoid a similar situation to last summer when they missed out on signing a number of players before eventually settling for Marouane Fellaini on deadline day. One of the areas that is most likely to be strengthened is at center-back, with Rio Ferdinand having joined Nemanja Vidic in departing at the end of his contract. And Van Gaal could bring with him to Old Trafford one of the players currently under his charge in the Netherlands camp.

The Manchester Evening News has reported that Bruno Martins Indi is one of the players under consideration. The 22-year-old was handed his international debut under Van Gaal and went onto play a significant part in the World Cup qualifying campaign, while establishing himself in the Feyenoord side. His versatility, having also operated at left-back, may also appeal.

The Manchester paper also again lists Borussia Dortmund’s Mats Hummels as being one of the defenders on United’s radar. The Germany international has long been linked with many of Europe’s top clubs and continues to be so, despite an injury-hit season. It is highly unlikely that he will be moving this summer, however. Having already lost Robert Lewandowski to Bayern Munich, Dortmund will steadfastly resist losing another key player.

That stance also means that Manchester United are likely to have to forget about signing Hummels’s Dortmund and Germany teammates Marco Reus. The attacking midfielder, whose performances have doubtless attracted the attention of many of Europe’s top clubs since moving to the Westfalenstadion two years ago, is believed to feature prominently on United’s list of targets. Reus, though has now confirmed that he will be staying where he is for next season.

“It's safe to say I will be playing for Borussia Dortmund also in the 2014-2015 season," he told German publication Kicker. “Basically I do not need to stress all the time that I am feeling great being with the club. As far as leaving (Borussia Dortmund) that is no issue for me, and I am not affected the transfer release clause.”
