Arsene Wenger has lavished praise on David Ospina despite reports claiming Arsenal are monitoring Chelsea goalkeeper Petr Cech, with the French manager expected to sign a new number one during the summer transfer window.
The Colombia international moved to the Emirates Stadium in summer 2014 from Ligue 1 side Nice for around £3m ($4.7m) after an impressive World Cup with Colombia.
And even though an injury earlier in the season hampered his adaptation to the Premier League, the 26-year-old keeper became the Gunners' number one after Wojciech Szczesny reportedly smoked in the showers following the New Year's Day loss at Southampton.
Ospina has since started 17 Premier League games, conceding only 10 goals while securing eight clean sheets in the process.
But a number of pundits and former club players, including Arsenal legend Thierry Henry, have urged Wenger to sign a world-class keeper this summer in order to compete with Chelsea, Manchester City and Manchester United for the title next season.
Reports have since linked Real Madrid number one Iker Casillas and Petr Cech, who is out of favour at Chelsea, with a summer move to the Emirates Stadium.
But Wenger has insisted on a number of occasions that he is not planning to sign another 'keeper, while after the 0-0 draw against Sunderland on 20 May, he took the opportunity to praise Ospina.
"Ospina has been absolutely great since he played and he has shown that again. In one against ones he has shown that he is outstanding," Wenger said.
Meanwhile, the manager has expressed his frustration after his side failed to score against the Black Cats, an occurrence for what is the third consecutive home game, despite dominating much of the match.
"It is frustrating because we had 75% possession and 28 shots on goal but we couldn't score," he told Arsenal Player. "We didn't really look like scoring and we lacked a bit of sharpness, change of pace, speed in our movement and Sunderland did the rest.
"We gave a lot at Manchester United and you could see that we had not completely recovered. It shows how vital the point was at Manchester United, to get three points in front of them, and now we have to finish well on Sunday – that's important."
