Celtic could finally lose out on Marcelo Saracchi as Houston Dynamo are back in talks with Boca Juniors and this time they look ready to finish the job. They want him gone, Houston want him in and Celtic have left the door wide open for somebody else to take him. Celtic still need proper cover for Kieran TierneyCeltic can look elsewhere because Saracchi is not the only left-back available. Tierney’s fitness will always have to be managed carefully and Celtic will need somebody who can come straight into the team without the level dropping through the floor. If Celtic let Saracchi go, the next left-back has to be better.
