It’s now Bale vs Neymar

4 years ago, when Ronaldo joined Real Madrid and confronted Lionel Messi, we thought nothing can top this. I mean seeing Ronaldo and Messi head to head in the same league was exhilarating enough, but now arrival of two best promising youths into the team has doubled the excitement, and tripled the anticipations. Neymar, already dubbed as the next Messi arrived in Barcelona earlier in the transfer window, while Bale was brought at the last moments to fill up the void created by the departure of Ozil and Kaka. The ‘transfer market enthusiasts’ were behind Bale from quite some time; well he’s a good catch and will prove that in no time.
It’s pretty safe to predict Bale to be a successor of Ronaldo (if he ever caved in to the homesickness he has for Old Trafford). Madrid seems to be one fully balanced team. Though fans aren't very thrilled by the selling of Ozil to Arsenal, but with Isco and Di Maria performing well, they might not even miss him once the season's on the way.
Tottenham have really dealt well with Madrid's negotiators to have extracted 85.3 M£. With that price tag, Bale has crossed Ronaldo's amount of 80M£ (paid in 2009), not accounting for inflation.
The Champions League has a solid chance to be in possession of one of these teams at the end of this year.

La-liga has never been so awesome and the rivalry between the two giants was never so fierce. The expectations have even superseded EPL limelight and it would be a treat watching how everything pans out.

As a matter of fact, both have started the season well, with wins without fault. In fact, Bale scored on his debut, promulgating his arrival and making a solid mark to commence another rivalry that will go long way.
