Like several of his Colombian teammates, David Ospina turned more than a few heads with an impressive World Cup this summer.

But perhaps the most important head he turned was that of Arsenal manager Arsene Wenger, as the club have finalised the transfer that will send the Colombian keeper from Nice to North London.

The club's official website confirmed the agreement: "David Ospina will join Arsenal Football Club on a long-term contract for an undisclosed fee."

Arsenal had reportedly been monitoring Ospina for some time, per the Mirror's Alan Nixon, but his solid showing at the World Cup—and his reasonable price tag—was enough to convince the Gunners to pull the trigger on a move to bring him to Emirates Stadium.

The keeper had spent the last six seasons with Nice, but in May declined to extend his contract, which was set to to expire after the 2014-15 season. Presumably, that decision was made with the hope of moving to a bigger club in the next year. 

If that was his intention, his wish was granted.

Ospina made 29 starts a season ago for the French club, earning a 7.19 average match rating from WhoScored.com for his efforts. He was even more impressive in five starts in the World Cup, helping lead Colombia to the quarterfinals and earning an average 7.26 rating.

With Arsenal, however, Ospina will have to fight for the starting gig. At the moment, the incumbent keeper is Wojciech Szczesny, but Arsenal may not have just brought Ospina aboard to push him.

They may have also bought an upgrade.

Matt Spiro of beIN Sports certainly thinks so:

Juan Arango of World Soccer Talk agrees:

Statistically speaking, the two provide an interesting comparison. 

The stats below would suggest that while Ospina's defense kept him busier, he was more proficient in keeping balls out of his net. On the other hand, supporters of Szczesny would rightly argue that he played against better competition in the Premier League. 

Still, statistically speaking, Ospina was in rarefied air a year ago, according to David Wall of OptaJean:

Not too shabby. Szczesny is a solid keeper in his own right but has a fight on his hands this season. That is why this signing is a win-win for the Gunners—either they've purchased an upgrade at keeper on the cheap, or they've bought an extremely talented deputy on the cheap who will push Szczesny to further heights. 

This signing won't move the needle like the additions of Alexis Sanchez and Mathieu Debuchy did, no, but it could end up being one of the most important decisions of the summer for Wenger and Company.
