Manchester United are preparing a double swoop for Bruno Martins Indi and Mats Hummels as replacement for Rio Ferdinand and Nemanja Vidic, according to the Daily Express.
Feyenoord centre-back Martins Indi has emerged as a prime target for United after the Dutchman's impressive performance at the national team, notching up more than 100 appearances with the club.
The Red Devils, who are set to move forward with the announcement of Louis van Gaal as their next manager in the next few weeks, have already earmarked targets for the summer as they look to return to the Champions League football, after finishing seventh in the league following the retirement of Sir Alex Ferguson.
The 22-year-old is a great prospect and will fit well in the United set-up, which is set to lose two of their most deferential figures at the back.
Vidic and Ferdinand have won a total of 11 league titles among themselves and have been the best defensive pair in the league for the better part of a decade.
United are also looking to bring in Mats Hummels as his partner in defence, with the player excelling with Borussia Dortmund since his transfer from Bayern Munich.
Van Gaal is acquainted with the player since his time in Munich and is willing to bring him to Old Trafford to secure a stable partnership at the back.
However, in spite of the pair leaving, the Red Devils do not have a dearth in quality with the likes of Jonny Evans, Phil Jones and Chris Smalling.
Vidic believes that United can promote from within and use the money to replenish in other areas.
"I have been training and playing with these guys and they definitely have all the ability they need to become top players," Vidic said.
"Chris and Phil are attracting a lot of interest here because they are national-team players and the future of English football, not just Manchester United.
"They definitely have the physical strength, pace and technique to play for this club and now is the time for them to step up and form the new partnership with Jonny Evans.
"Those three have to be the players who are carrying on and becoming the United defenders for the next seven or eight years. They have that capability and the experience to step up," he added.
