VIDEO: Latest blunder from Arsenal target shows why Wenger should avoid bid

Real Madrid goalkeeper Iker Casillas has had his fair share of struggles in recent times, and his latest blunder against Slovakia was another nightmare for him.

Spain's woes from the 2014 World Cup don't appear to be ending soon. Vicente del Bosque's side crashed out of the group stage in Brazil after embarrassing defeats to the Netherlands and Chile, and their qualifying campaign for the 2016 European Championships hasn't gone much better.

Tonight's loss to Slovakia was another nightmare evening for Del Bosque and co, with Miroslav Stoch clinching a late winner in a famous night in Bratislava.

Yet Slovakia's quest for a win was helped massively by Iker Casillas. Formerly considered as the best goalkeeper in the world, Casillas' struggles over the last two years have been well documented. Firstly dropped by Jose Mourinho, Casillas was then made second choice by Carlo Ancelotti too as he struggled to displace Diego Lopez between the sticks for Real Madrid.

Then his disastrous World Cup and his susceptibility on crosses mean that Casillas is widely thought to be a hindrance for both club and country, and it showed again tonight. Juraj Kucka's long range free kick appeared to be heading straight down Casillas' throat, but he somehow left the ball through him and in to the net.

Recent speculation has linked the 33-year-old with a move to Arsenal, but tonight's latest horror show jsut proves that Gunners boss Arsene Wenger is better off sticking with the likes of Wojciech Szczesny and David Ospina rather than overpaying for someone who is clearly past his best.
