Jose Mourinho says Manchester United will need to spend big this summer to improve their squad ahead of next season.

United currently sit sixth in the Premier League table, seven points off the top four.

Mourinho spent £157 million on transfers following his appointment at United last summer, and he says they will need to do something similar this year.

"We had just one transfer window, we didn't use the second transfer window [in January]. We need a big transfer window again," Mourinho is quoted as saying by the Sunday Mirror.
