Tottenham face a battle to sign Newcastle United goalkeeper Fraser Forster.
The Daily Express says Tottenham are also keen on Forster, along with James Forrest, and have watched him in recent weeks but if they were to try and sign Forster then they would need to buy-out Celtic's options.
A transfer fee, in the region of £2 million, was agreed between the two clubs back in the summer. Any permanent deal would now require Forster to agree terms with Celtic and so far those discussions are still to be opened.
