Manchester United boss Ole Gunnar Solskjaer admits they've focused on rebuilding their defence.
With the additions of Aaron Wan-Bissaka and Harry Maguire this summer, as well as David de Gea's contract extension, Solskjaer believes he is finding a winning formula.
"David de Gea has been unbelievable for us in the years he has been here," Solskjaer said.
"We signed Harry Maguire in the summer, a massive signing. Victor Lindelof signed a new contract.
"Aaron Wan-Bissaka is young and up-and-coming. Luke Shaw is young. Axel Tuanzebe is young - we have something to build on there. The foundations are being built from the back.
"We know we haven't created enough going forward but when we have David in goal sometimes 1-0 is enough for us."
