West Ham United had reportedly agreed a deal in principle with Arsenal over the transfer of left-back Kieran Tierney. However, the player is favouring a move to his former club Celtic instead. It seems West Ham were unable to get a deal done for Tierney, despite reaching an agreement with Arsenal. This information is according to Hammers News, citing journalist Graeme Bailey.

West Ham United have shown interest in acquiring Arsenal defender Kieran Tierney, having made an inquiry about the player who is currently out of favor at Arsenal. However, reports indicate that Tierney has expressed a preference for returning to Celtic. It is said that Tierney is engaged in pre-contract discussions with Celtic, as his contract with Arsenal is set to expire at the end of the current season. Since transferring from Celtic to Arsenal for £25 million in August 2019, Tierney has faced challenges, including fitness issues and a decline in his standing within the team. Despite West Ham's interest, it seems that Tierney prioritizes the chance to return to his homeland.
