Louis van Gaal assistant Ryan Giggs says Manchester United will try to strengthen in all areas of the pitch during the summer transfer window.
After a slow start to last season's campaign, the Red Devils enjoyed a very positive second half of the season which allowed them to finish in the top four.
They will feature in this season's Champions League if they make it through the play-offs where they could face the likes of Lazio, Sporting Lisbon, CSKA Moscow and Monaco.
And Giggs believes depth will be a much-needed element in the squad.
"If there are players available who are winners, who are proven, then, yeah, let's go and get them," Giggs is quoted as saying by FOX Sports.
"And with any good team the spine is important. Midfield, striker, center-backs, goalkeeper. I'm sure we'll be looking to strengthen the spine all the way through.
"We obviously need to strengthen because we were fourth. We weren't first, second or third.
"And the teams above us will strengthen, too. There's the added challenge of the Champions League, and we need players that are going to improve us.
"But we're not too far away.
"We had a great record last season in the big games and the problem was the consistency. We dropped points we shouldn't have and got off to a bad start.
"We drew a lot of games away from home against teams we should have been beating.
"You tot up the games you think you should have won and think, 'Yeah, we should have been much closer' – but you have to go out and do it, and in the Premier League that's not easy."
