The loss of Robin Van Persie may come as a huge surprise to many Manchester United fans - but current boss van Gaal insists their is no panic to sign forwards.
Captain Wayne Rooney, Javier Hernandez and James Wilson are the three remaining strikers at United. The manager says he is 'not worried about that position' reports SkySports.
Dutchman van Gaal has tipped Rooney to become the Red Devils main striker, a position where he has not played consistently for three seasons - since the arrival of Robin van Persie.
Last season Wayne Rooney grabbed top goalscorer with 14 goals, Van Persie achieved runners-up with 10. ESPN note that United are in dire need of world class goalscorers and may be interested in Spurs' Harry Kane.
Javier Hernandez lost his place in United's first team in 2013 which resulted in a loan move to Real Madrid the following season. His game time remained low as he only started 16 times but scored 7 goals.
The exit of Robin van Persie and Radamel Falcao gives the Mexican an opportunity to 'prove himself' for the Red Devils without the added competition.
The addition of Memphis Depay, who joined from PSV after finishing top scorer in the Dutch Eredvisie last season is surely a great signing for Manchester United. The Dutchman's attacking attributes allow him to play as a striker, winger or central midfielder.
Van Gaal is no stranger to big money signings, adding Angel Di Maria to the ranks last season for £59.7m. He has hinted at a surprise transfer, which has prompted links with Real Madrid's Gareth Bale and Bayern Munich's Robert Lewonanski.
Whether Man United sign a superstar centre forward or not - one thing is certain, Van Gaal has given the squad a much needed boost and we expect them to challenge Chelsea and Man City for the title.
