I hate this move. Benzema has played brilliantly for us lately. Yeah, he's struggled but his passing and crosses have given Ronaldo and Bale opportunities. I don't know why Madrid is so interested in Suarez. All this is gonna do is send Morata packing too. Granted, this transfer would give Real a three-headed attack beast but I'm not certain this move would be beneficial in the long run.
Don't worry. Arsenal has been "going to sign" Benzema since like 2012. Wenger will lowball Madrid and inevitably settle for some obscure French striker currently playing in Eredivisie.
Madrid are interested in signing Suarez because of the money it will bring. While they are currently the favorites to win the Champions League, if they signed Suarez they'd be favorites to win just about everything next year too. They'd also get the kit sales, player unveiling, and everything else that goes with such a massive signing. It's very valuable to them. This is all assuming that he doesn't bite or racially abuse anything, of course.
