Ronadlo
Had offloaded Louis Saha in the very 1st transfer window and all I had was Rooney and Tevez.
I needed someone who was reliable and all of a sudden Ronaldo (The Real One

)snubbed down a contract from Milan, and after long negotiations and praising in the media, I was able to seduce him to Old Trafford.
The guy wasn't in a position to play in January, but after a month of intense training he was back to full fitness and over the next couple of months was busy providing assists to fellow strikers.
Hattrick against Barcelona ( after that You can make the difference talk ) in the Away Leg of Champions League - which allowed us to win 5-4 on aggregate , A brace in FA Cup final against Blackburn, and 3 late winners against Chelsea, Sunderland and Tottenham proved his worth to the team.Monetarily speaking I landed him for free from AC Milan abt 6 Million in compensation, and that too after a Wage slash, and after the first season he had reclaimed his place in the Brazilian National squad and clubs like Liverpool and Atletico were interested in signing him.His value stood at USD16M. Profit

.Though I didn't sell him.
Leonardo
I don't remember the club where I signed him from ( I deleted the Save game after it crashed after my 3rd season). But I got him for around $3 Million .A Left Winger and Forward, he was just a player whom I bought just for the sake of exploiting his high Dribbling and first touch stats as well as pace. Took some time to settle but as soon as he romped home his first goal , he has become a Super Sub.Has often replaced Giggs in the starting Line Up, as well as covered up for Tevez and Rooney.Price went upto abt $17M after two seasons.
Baptista
After the end of my second season, expectations were high
coz the only trophies missing from the cabinet were the Community shield '2007 and Premier League 2007.In 2008 our Devils had achieved everything.But my primary objective was to bale out the club from possible financial trouble.So cost cutting was at its best.Pique was sold for $50M to Barcelona, (thrice his value).Strikers were Tevez, Rooney,Ronaldo, Fagan and Campbell and I was inclined on relying on them, when out of the Blues, Real offered me Baptista for $3Million, even when I hadn't shown any interest.So I brought the guy to OT, just for the sake of offloading him after making some handsome profit.But in his debut match I introduced him in 60th minute and he responded by thumping in 4 goals against Liverpool.And by the end of the season had banged in 30 goals in abt 35 appearances, most of them as subs.
So these were the signings for me so far.
