Palace and West Ham battled in the Premier League on Saturday afternoon - a game which West Ham 3-1 - but they now look set to lock horns once again, this time in the transfer market.
The Daily Star believe that both clubs will have scouts attending the game between Belgian sides Oostende and Club Brugge, with striker Cyriac the man in demand.
The 25-year-old striker had thrived at Standard Liege, but after a quiet spell with Anderlecht, the newly-capped Ivorian international signed for Oostende over the summer - and his move has been a roaring success so far.
With nine goals in 12 starts, Cyriac has fired Oostende to the top of the Belgian Pro League, and they can now prove their title credentials with a win over Club Brugge today.
Cyriac will seemingly be the focus of attention for scouts, with Palace and West Ham both believed to be considering January moves for the player.
At 5ft 8in, Cyriac is far from the biggest striker, but he has pace to get in behind defences, which is understandably appealing to Premier League clubs - but having struggled at Anderlecht, teams must make sure that his remarkable goalscoring run isn't just a purple patch before making any bids in January.
