A highly defensive formation with five midfielders and a lone striker.
The 4-5-1 is one of football's most defensively minded formations, featuring a back four, a packed midfield of five, and a single striker. This system is designed to deny space, protect the penalty area, and frustrate attacking teams. The five-man midfield creates a solid block that is difficult to penetrate, making this formation ideal for underdogs facing superior opposition. When defending, the 4-5-1 becomes incredibly compact, with two banks of four and the striker dropping to create a third line. In possession, the formation can morph into a 4-3-3 with wide midfielders pushing high. Mourinho used this system effectively at Porto and Inter Milan, while it remains popular for teams protecting leads or facing teams with superior quality. The lone striker must be exceptional at holding up the ball and bringing teammates into play.
