The Arsenal goalkeeper has become a key man for Arsene Wenger ahead of the match with Chelsea.
Having started the season as backup to Wojciech Szczesny, the former Nice man only had a couple of cup and European appearances to his name, with his availability greatly hit by a couple of injuries.
But since the turn of the year, he has displaced the Pole, and impressed as Arsenal soared up the Premier League table, and they currently sit in second place.
“I have to thank all the fans for the experience they’ve given me," the 26-year-old said. "It’s been important to me and this team, and has been a great source of pride for me. As I’ve always said, I will always try my best and dedicate myself to the team, and I hope I will be able to give my all until the end for Arsenal.
“I adapted to the English style and the style required by the team quickly. I tried to put it into practice in the role I play in the team, in the best way possible."
Ospina has been part of a successful Arsenal team in the league in 2015, losing just one game since making his league debut against Stoke on Jan 11. With the Colombian in the team, the Gunners have failed to win just once, an extraordinary record that has garnered 11 victories from 12 matches. Their loss against Tottenham in the North London derby was the only blip, and since that match Arsenal have won eight on the trot, a quite outstanding record.
Despite the length of that run, the goalkeeper feels Arsenal possess the players to ensure they don't lose sight of their goals, crediting manager Arsene Wenger for the way the season is going.
“We have excellent players at our disposal but now we have to keep on track," he added. "We have a brilliant manager in charge who has been able to put us on course for where we want to go.
“The defence I play with is full of experienced players who have played many games in strong national teams. It has helped for sure. We take pride in doing things well and I’m sure we can achieve a lot.”
The goalkeeper was rotated for the FA Cup win over Reading, with Szczesny coming in during the 2-1 win, but Ospina is likely to be back between the sticks when Arsenal host league leaders Chelsea on Sunday.
