LONDON, Feb 22 : Crystal Palace manager Oliver Glasner insisted he retains the Premier League club's backing after supporters unfurled a banner calling for his dismissal during Sunday's dramatic 1-0 victory over bottom side Wolverhampton Wanderers. Palace won after Evann Guessand scored in the 90th minute against 10-man Wolves, lifting them to 13th in the table. During the game, a protest banner at Selhurst Park read "Opportunities missed - board inept. Fans disrespected - Glasner finished."
