In summer 2011, when Papiss Cisse was playing for SC Freiburg—having scored 22 Bundesliga goals in 32 games last season—no club was willing to take a chance on him.
That's because he was valued at £14 million, a fee which no manager or board of directors was willing to pay, especially for a player who previously had less than 30 games of top-flight experience—despite being a professional for seven years.
Many sides were said to be interested—and a few sent scouts—but no club was brave enough to make a bid, and the summer transfer window went by with no big move for the striker.
And come the January transfer window this season, clubs were again reluctant to pay significant money for the player, who, disappointed not to have moved in the summer, was producing a slightly lower goal rate of nine goals in 17 games.
Manager Alan Pardew put great faith into Cisse and signed him up on a five-and-a-half-year contract.
The Toon were the only club that really took a chance on the striker and allowed him to play on a bigger stage.
Twelve Premier League games later and the 26-year-old Senegal international certainly hasn't disappointed, scoring 13 goals—including the greatest goal you'll ever see against Chelsea.
Here are five incredibly stupid clubs who, given where they are right now, will forever regret not paying up and signing Papiss Cisse when they had the chance.
