Free tip for the Emirates derby

Tonight we are continuing giving free tip for the major European competition, round of 16, 1 leg game.
Barcelona is on the great way of becoming the first club defending their title since the Champions League is introduced with the new format. The best MSN (Messi-Suarez-Neymar Jr.) trio in the world at this moment seems to give many problems to the goalkeepers, who like a joke are scoring goals in almost every game (well...except for the last one). However here we are expecting a total different approach to the game, where Arsenal will try at least to hold the champions with a draw.
At the Emirates stadium these two teams have met twice. Arsenal recorded a minimal win while the other game ends in a draw with four goals scored. Hopefully tonight both teams will produce the same entertainment football for us.
