The midfielder is believed to be a target for several clubs who all want to take him on loan, a scenario that is very unlikely to happen. If he were to leave Pochettino would almost certainly want to sell him or loan him with a guaranteed purchase option at the end of the loan spell.
It is far more likely that any decision on his future will be left until the summer. He may have only just signed but he would join a list of players who have been shown the door after failing to impress on their first season with us. Others we have tried to sell, been unsuccessful and had to wait a further year to get rid of them.
