Manchester United earned back qualification into the Champions League in the first season under the management of Louis van Gaal.
However, the job is about to get tougher now. The Red Devils must splash cash to sign world class players and compete for the Premier League title next season.
Not only that, they must look to go far in the Champions League against the best teams around as well.
Manchester United had a massive midfield conundrum under David Moyes but the rejuvenated form of Herrera and Fellaini has helped United a lot this season.
However, Van Gaal still wants to improve the depth and quality of midfield and a versatile German is in the limelight for that.
According to reports, Manchester United have reached agreement to sign Ilkay Gundogan from Bundesliga side Borussia Dortmund in the summer transfer window.
Although price is not mentioned in the above given link but previously it has been reported that the fee might be 30 million Euros for the Germany international.
