It is reported that Alex Ferguson the famous Scottish manager who was manager of Manchester United till the year 2013.; He was the most successful manager in the E,.P.L history. And very sadly after his departure into retirement Manchester United were never ever the same club i any form under both david Moyes and Louis Van Gaal. But what we must take into consideration is that Sir Alex Ferguson is now 75, seventy five years old and has had heart problems in the past , and with out players of the class of David Beckham , Ryan Giggs, Paul Scholes, Gary Neville ,. I strongly feel sir Alex Ferguson should not come out of retirement. He said he would join Manchester United if the club sack Louis Van Gaal.
