Latest domestic information
• Sunday 5 April: Manchester United FC 3-2 Aston Villa FC
[Ronaldo 14 80, Macheda 90; Carew 30, Agbonlahor 58]
United were without Rooney, Paul Scholes and Nemanja Vidić through suspension yet took the lead when Ryan Giggs tapped a ten-metre free-kick for Ronaldo to fire in. The visitors drew level when John Carew rose above Gary Neville to head in Gareth Barry's right-wing centre before Carew crossed for Gabriel Agbonlahor to head Villa in front. The home side were on course to suffer a third successive league defeat for the first time since December 2001, only for Ronaldo to lash in a fine equaliser before 17-year-old debutant Federico Macheda curled in in added time to secure a victory that took the champions back above Liverpool FC at the top of the table.
• "We've been over this ground many times; the drama, the fans, the celebrations – you want to see that," said Sir Alex Ferguson. "[At 2-2] I thought 'gamble' – winning is what the game is about and we deserved the win today because we took a chance. We didn't defend well but we always looked like scoring and that's always exciting. At this time of year teams drop points: we've had a blip but we're back today, despite having eight players missing."
• United have conceded eight goals in their last three league games – more than in the previous 23 put together.
• Macheda replaced Nani after 61 minutes to make his senior debut for United. He had struck a hat-trick for United's reserve side against Newcastle United FC on 30 March, completing his haul a minute from time to earn a 3-3 draw.
• United's eleven-match winning run in the Premier League had come to an emphatic end on 14 March as they went down 4-1 to Liverpool at Old Trafford despite taking the lead through Ronaldo's 23rd-minute penalty. Goals from Fernando Torres [28] and Steven Gerrard (44) turned the game around before Vidić was sent off with 14 minutes left, leaving Fábio Aurélio (77) and Andrea Dossena (90) to complete a miserable afternoon for the home side, who had last tasted defeat at Old Trafford in the FA Cup quarter-finals against Portsmouth FC on 8 March 2008.
• The Liverpool loss was United's first at home in the Premier League since a 2-1 defeat by Manchester City FC on 10 February 2008, and their heaviest home or away since a 3-0 loss at AC Milan in the UEFA Champions League semi-final second leg on 2 May 2007. United had not lost by a three-goal margin at Old Trafford since a 3-0 reverse against Chelsea FC on 1 December 2001.
• Nine-man United went down again against Fulham FC on 21 March, losing 2-0 at Craven Cottage to end a 45-year unbeaten away record against their opponents. Scholes was shown a red card for handball in conceding the penalty from which Danny Murphy gave Fulham an 18th-minute lead and Zoltán Gera wrapped up the win three minutes from time, Rooney collecting a second yellow card two minutes later.
• United had not lost successive league games since defeats at Norwich City FC and Everton FC in April 2005.
• The Liverpool loss ended United's unbeaten run of 16 matches in all competitions, of which 14 had been won. They had lost only once in 31 games prior to that defeat and had claimed 19 victories in their previous 22 games in all competitions.
• Liverpool's victory also halted United's nine-match winning streak at home since a 2-2 draw with Aalborg BK on Matchday 6. United have won all bar four of their 23 home games this season, drawing three and losing to Liverpool.
• Peter Løvenkrands' goal for Newcastle on 4 March was the first conceded by Edwin van der Sar in the league in 1,311 minutes, since Samir Nasri's 48th-minute strike for Arsenal on 8 November. Former Club Brugge KV goalkeeper Dany Verlinden holds the European record for the longest run without conceding in a European top flight having gone 1,390 minutes unbeaten in 16 matches from 3 March 1990 to 26 September 1990.
• Roque Santa Cruz's goal for Blackburn Rovers FC on 21 February was the first United had conceded in the Premier League in 1,334 minutes, a match for which Van der Sar was rested. They had kept 14 consecutive clean sheets, but have now conceded in their last five league matches.
• Giggs registered the only goal in United's win at West Ham United FC on 8 February, meaning he has scored a league goal in each of his 19 seasons with the club. The Welshman is also the only player to find the net in all 17 seasons of the Premier League era.
• United will play Everton in the FA Cup semi-finals at Wembley on 19 April.

Latest domestic information
• Saturday 4 April: Vitória SC 1-3 FC Porto (Roberto 19; Farías 52, Mariano 58, Rolando 88 )
Porto extended their unbeaten run to ten matches in Guimaraes, but had to come from behind after going in at half-time 1-0 down. Ernesto Farías, who had been brilliantly denied by home goalkeeper Nilson early on, equalised as he headed in Meireles' cross and Mariano then diverted in Tomás Costa's wayward effort. Rolando sealed the points, heading in Lucho's left-wing corner.
• Ferreira made four changes to the team that had beaten CF Estrela da Amadora in their previous outing, with Helton replacing Nuno in goal and Farías deputising for the suspended Lisandro. Having returned from international duty only 24 hours before the match Lucho and Cristián Rodríguez dropped to the bench, coming on as second-half substitutes, as Tomás Costa and Hulk came in.
• Porto have won their last eight away games in the Liga, scoring 25 goals and conceding seven. They have been less impressive at Estádio do Dragão of late, drawing four of their last six league fixtures at home.
• Rolando's goal was his first in the Liga for Porto, though he did register against FC Dynamo Kyiv on Matchday 4.
• Mariano's goal was his second in as many Liga outings having also registered in Porto's return to domestic action following Matchday 8 on 15 March. Goals midway through either half from he and Lucho earned a 2-0 Liga victory at home to A. Naval 1º Maio. With Fernando and Hulk suspended, and Fucile, Freddy Guarín and Nelson Benítez ruled out through injury, Andrés Madrid and Mariano both started.
• It was only Lucho's third league goal from open play this season, his other six coming from the penalty spot.
• Seven days later Lucho was again on target in another 2-0 win, this time at home against CF Estrela da Amadora in the Portuguese Cup semi-finals.
