The swathes heading for Cardiff City exit, the players Bluebirds are targeting and the deals being worked on

Cardiff City are facing up to one of their most significant summer transfer windows in recent memory.

Alex Smithies and Marlon Pack have already confirmed they won't be here for the next chapter of the Morison project, with the latter recently linked with a reunion with Bristol City, while the likes of Leandro Bacuna, Josh Murphy, Ciaron Brown, Aden Flint and Isaac Vassell all seem certain to join them. The future of Will Vaulks looks similarly uncertain, with former club Rotherham United already mentioned as a possible destination, although that talk has since been cooled by Millers boss Paul Warne.

Out of all the players coming to the end of their current deals, it's understood that Joe Ralls is the most likely to be kept on, with the midfielder already offered a contract on reduced terms. Sean Morrison is another who could yet be kept on a short-term basis as he bids to return to full fitness, but the choice appears to be down to both players as to whether they are willing to stay or not.

In terms of the loanees, it seems unlikely that Alfie Doughty, Jordan Hugill
