After the highs of London 2012 in which Mexico won the gold medal, few would would have expected them to struggle for the World Cup here in Brazil. They only managed 2 wins out of 10 in the group phase of qualification, and relied on USA scoring a last minute winner against Panama to see them through to a play-off. One change of manager later, they won the play-off with New Zealand 9-3 by using only Mexico-based players. Now they stand here in Brazil as equals.
With a change of coach, tactics and personnel, it will be difficult to predict how the Mexicans will line up. I expect a change in goal, with Ochoa to be started, whilst Man United's striker Javier Hernandez to be left out of the starting XI with Dos Santos taking his place up top with Peralta. Other than this, there won't be too many changes to their qualifying game. In order for Mexico to get anything out of this game, they will need Guardado and Dos Santos to be in top form.
Cameroon suffered an early setback in their qualification, and needed an overturned loss against Togo to help them on their way, before a play-off win against Tunisia saw them packing their bags for Brazil. Samuel Eto'o will undoubtable be their key man in the tournament, but with Alex Song alongside Makoun and Mbia at the heart of the team, they will be very competitive in Brazil. They are usually strong in defence with the likes of N'Koulou and Chedjou organising the well-drilled back four.
I am predicting an open game, with Cameroon running out eventual winners 3-2
