Dean Furman helped his League One side Oldham Athletic spring a surprise on Championship outfit Nottingham Forest on Saturday.
The Latics overcame the odds to beat the hosts 3-2 in their FA Cup third round clash at the City Ground.
Matt Smith inadvertantly opened the scoring for the hosts in the 13th minute when he put the ball into his own goal.
However, a Robbie Simpson brace early in the second half put Oldham in control before Jose Baxter secured the victory. Billy Sharp could only manage a late consolation strike for the home team.
Furman was the man who set up Simpson's second goal in the 58th minute. The South African provided the telling cross that found Simpson who headed home.
Meanwhile at Elland Road, Davide Somma came on as a substitute for Leeds United as they were held to a 1-1 draw by Birmingham City.
Wade Elliott put the visitors in front but Luciano Becchio forced the tie into a replay with his leveller on the hour mark.
Somma came on for Alan Tate in the 79th minute of the clash.
