Brendan Rodgers has warned Chelsea they are wasting their time plotting a move for Craig Gordon.
The Celtic and Scotland keeper features on a three man contingency list of potential Stamford Bridge replacements should Asmir Begovic makes a £10million switch to Bournemouth.
Espanyol's Diego Lopez and Fernando Muslera of Galatasaray have also been listed as possible challengers for the first team jersey to Thibaut Courtois..
