Man Utd Transfers - 5 Right-Back Alternatives To Bacary Sagna Van Gaal Should Sign

4. Philipp Lahm

Though an unlikely option, Manchester United must aim high when targeting players this summer and there is no doubt Phillip Lahm is one of the best in the business today. The Bayern Munich full-back has been an ever-present for his side this season, helping them achieve Bundesliga success in record time and reach the semi-final of the Champions League. He also played for the Bavarians under incoming United manager Louis van Gaal, who is set to be announced as David Moyes's successor this week. And should van Gaal be successful in convincing his former player to move from Munich to Manchester, United would gain some much needed experience and authority at right-back to compensate for the loss of former leaders Rio Ferdinand and Nemanja Vidic. It may however take a leap in the imagination to envisage the highly-rated right-back forgoing European football next season, but if we're going to sign a right-back, we need to look at the best.
