Can the league leaders in the major competitions keep up their good form?

Since the winter break has come around I have wondered if the major leagues points leaders can keep up their form and stay atop their leagues. Here's my take on how they have done so far and what they must do to keep their form.

Ligue 1 (France): Paris Saint-Germain

Sitting atop the table in France is new soccer powerhouse Paris Saint-Germain. With the additions of Zlatan Ibrahimovic, Thiago Silva, Ezequiel Lavezzi, and Gregory van der Wiel, PSG have solidified themselves as a force to come for at least this season and next. Starting off slow in the league they hit stride with superstar striker Zlatan Ibrahimovic netting 19 goals in the league so far. With the recent arrival of Lucas Moura from Sao Paulo and the surprising signing of iconic midfielder David Beckham, PSG seem set to keep their spot atop Ligue 1. As long as Ibra can keep scoring and getting just a little support there is no reason that PSG should slip out of number 1.

Bundesliga (Germany): Bayern Munich

Sitting atop the table in Germany is powerhouse Bayern Munich. Off to one of the best starts in team history with 48 points and having only 1 loss in the league Bayern look set to stroll to their 22nd league title. The additions of Mario Mandzukic, Xherdan Shaqiri, Dante, Javi Martinez, and Claudio Pizarro have seen Bayern have an even deeper squad, something that plagued them last season. With the recent fitness revival of Mario Gomez and the spectacular play of Mandzukic, the strike force is even more deadly.

La Liga (Spain): FC Barcelona 

The leaders in Spain are (surprise, surprise) FC Barcelona. Sitting high atop the table, Barcelona are on pace to have one of their best seasons ever. With 58 points they are 15 points clear of arch-rivals Real Madrid and look unstoppable in the league. With Messi recently netting his 200th Barcelona goal and breaking the record for goals scored in a calendar year in 2012, Barcelona look to be in complete control in La Liga. Only a complete meltdown could kill their season, and we all know that won't happen.

Barclays Premier League (England): Manchester United

The Red Devils sit atop the Barclays Premier League, 7 points clear of cross town rivals Manchester City. Manchester United seem to be rolling, but a lack of defensive discipline could kill their title hopes. Having conceded their biggest amount of goals at this point in the season, and with goalkeeper David de Gea looking dreadful at times, Manchester United have relied on the strike force of Chicharito, Danny Welbeck, Wayne Rooney, and superstar signing Robin van Persie. Leading the league in goals, RVP seems to have picked up where he left off last season, on pace to score another 30 goals this season. United need to sharpen up their defense if they hope to survive comfortably in the second half of the season, but need not worry too much as long as van Persie and Rooney can keep scoring at the rate they are now.
