Could this factor prove to be Everton's eventual downfall in Europe?

Everton have made a steady start to life in the Europa League, as Roberto Martinez's side have four points in their opening two fixtures.

The Toffees snatched a late draw against Krasnodar, thanks to Samuel Eto'o's 83rd-minute strike, and after beating Wolfsburg 4-1 in their first match of the group stage, they sit comfortably at the top of the table. However, cracks have shown throughout their European campaign, as the statistic below suggests.

Already Martinez's side have been guilty of more defensive errors than any other side in the competition; a worrying statistic for the Goodison faithful. Should this record continue over the coming group matches, then they could find themselves undone, especially when playing away from home. 

The Toffees gifted Krasnodar the lead when Jagielka's ill-judged touch on Odil Ahmedov's pass put Ari through on goal to slot in the opener, and there can be no denying that this error cost the club a further two points. With Lille and Wolfsburg drawing in Thursday night's remaining Group H fixture, they failed to take advantage. 

Defensive lapses have cost the Toffees in the league this season, too. Already the club have conceded 14 goals, a total greater than any other top flight side, while Tim Howard has just one clean sheet from nine appearances. 

Something needs to give if Martinez's side are to reach the heights of last season.
