Ashley Young was the right signing at a good price for United but I still think they need more in midfield to complete the jigsaw.
Young is going to have to hit the ground running - Antonio Valencia did really well coming back from serious injury so quickly and his only poor game was, unfortunately, in the Champions League final.
Young has something extra in that he can cross the ball and is brilliant with set pieces, which will help United as they haven't been relying so much on crosses of late.
He may have to change the way he plays a little but United may do so too if they are going to get the best out of him.
I think such a big move will help him reach his potential too as I think he was possibly treading water a bit at Villa, as he wasn't quite as consistent last season. He will need to work on that as United demand consistency almost as much as they do ability - just look at Dimitar Berbatov, and Nani, the man whose place Young is expected to take.
Nani seemd to have turned it round this season, becoming more consistent with his level and decision-making and it looked at one point that he'd win the football writers award.
But he lost his way and went missing at the end of the season, although wasn't helped by that injury, and he lost his place in the team.
With the added pressure of Young, Nani is going to have to step it up, while Valencia will have to maintain the pre-Barca performances as he's not guaranteed a place.
All three are going to have to start the season very well, and don't forget Ji-Sung Park can play in both those positions too.
But as I said earlier I think United need a big player in the middle as, with Paul Scholes gone and Ryan Giggs at the tail end of his career, they'll need someone with a presence, someone who can take a game by the scruff of the next. Someone in the mould of former captain Roy Keane.
United need the kind of player who can drive them on to win the tight away games - and matches such as the Champions League final - which is something that, for all their organisation and pace on the counter attack, they lacked last season, as seen in the number of draws outside of Old Trafford and, crucially, the defeat to Barca.
They will be looking for a central midfield player, a creative payer - they'll need more than Michael Carrick and Anderson perhaps isn't quite creative enough for that role.
I thought Charlie Adam did okay for Blackpool but I personally don't think he's what Manchester United are looking for in terms of personality and consistency - his agent is obviously doing a good job touting him and almost got him a move to Liverpool but I can't see him in a United shirt. More likely he will move later in the window, for a lower fee, and join a top-six team.
So who do United sign, the final piece in the puzzle? It's a million-dollar question. So many players are being mentioned but as soon as a name is brought up City get linked because of the money.
You can go to a club like United and become overwhelmed - suddenly a player can question his ability because of the competition and the pressure. It almost favours the younger players, who are given time by the fans and have the capacity to learn from Fergie, but an established player needs a big, strong personality to match his talent.
Nothing's really happening yet but you'll start to see some movement when the players come back from holidays this week and next. Fans tend to panic at this stage, but it's always been the case that big transfers are concluded late July or even August, unless they are deals that have been in the pipeline for a while - such as Young, Phil Jones and now David de Gea.

The other big story I suppose has to be the return of Andre Villas-Boas to Chelsea.
The scout is now the gaffer and I don't think anyone really knew of him when he was working for Jose Mourinho as he wasn't even his most senior aide.
But he's come to the fore in his own right, and Roman Abramovich obviously trusts him to ' do a Mourinho' and shake the squad up.
It's as much about putting players out to pasture as it is about bringing in new faces as there is a dressing room issue where certain players dominate without being at the peak of their abilities any more.
Carlo Ancelotti didn't suddenly become a bad manager after doing the double. I think everyone knows what goes on in Chelsea's dressing room, that some men have too much influence when their careers are on the wane - Ray Wilkins was key in managing that in the past and it's no surprise to me that some people are linking him with a return, though I see it as unlikely.
Andre will need to crack a few heads, show everyone who's boss and get shot of a couple of the alpha males. New players will come in, and some will go, I think it's obvious who Chelsea could do without.
Didier Drogba, great player though he is, may have done his time and at his age they could cut loose and focus on a certain Spaniard, who I worry is being drowned out by Drog's type-a personality.
Maybe it's time for Frank Lampard to try a new challenge, possibly in Spain, while I'm not sure Salomon Kalou and Nicolas Anelka have so much to offer any more, given their high profiles.
Fernando Torres may or may not be the man for Chelsea in the long-term but the new manager has to work with him, try to make him feel like he's the number one and at least get him back on track.
Long-term I think John Terry, while Chelsea through and through, will have to be depended on less as his body isn't coping as well as it did.
And anyway, for me the defensive solution is Alex and David Luiz, particularly with the lack of pace Terry has. I thought when they played together last season they showed great understanding and both had the speed to play the offside drap.
I'm not sure you can force a player of Terry's standing out of Chelsea, and I don't see the need to, but you may see him used less and less over the season.
