Louis van Gaal's bold recruitment drive appears to be gathering momentum after it emerged that Ilkay Gundogan expects to complete a £15million move to Old Trafford at the end of the season. Despite already re-shaping Manchester United's fortunes and guiding them to third in the Barclays Premier League, ahead of the derby with City, Van Gaal is pressing ahead with plans for more big name signings this summer. Sportsmail revealed last week that Germany centre Mats Hummels has indicated he's finally ready to become a United player, and it now seems it will be as part of a £50m-plus Borussia Dortmund double after Gundogan also gave Van Gaal the go-ahead to bid for his services.

Mats Hummels (left) looks likely to join Manchester United this summer to strengthen their porous rearguard . Hummels and Gundogan are likely to be lining up in red for United next year if Van Gaal gets his way . United are believed to have responded to the signal from the Germany midfielder and are confident of agreeing a fee with Dortmund. Both players have been on United's radar for some time, and both have privately let it be known they feel the time has arrived for a fresh start. Dortmund bosses are resigned to Gundogan following Hummels out of the door after the midfield anchorman flatly refused to renew a £100,000-a-week contract that runs out next year and evidently made little secret of his wish to join United. At the age of 26, Hummels (right) has made 39 appearances for Germany and won the World Cup last year . Van Gaal is set to be handed a £150m transfer kitty to further strengthen United in his second year at the club . A powerful figure at the base of Dortmund's midfield, Gundogan might normally have cost a sizeable chunk of Van Gaal's £150m summer budget but could be prised away for as little as £15m, given the time left on his contract. Dortmund will ask for around £36m for Hummels.
