Sebastian Larsson's agent has warned Stoke they face competition from Italian and Spanish clubs if they make a move for the midfielder in January.
The Potters are planning a move for the 25-year-old if they fail to tie down Jermaine Pennant on a permanent contract.
Real Zaragoza are asking for £6million for Pennant, and if Stoke are unwilling to pay they may turn to Larsson, who is out of contract at Birmingham in the summer.
Larsson's agent, Per Jonsson, said: 'Seb likes to be in England, but Spain and Italy are good countries tobe in and I know clubs there have been watching him.
'I know they have followed him this season and liked what they have seen.
'There are a lot of clubs that like him, but we have not discussedanything with other clubs. I really don't know what will happen inJanuary.'
Jonsson also revealed the midfielder had not given up hope of negotiating a new deal to stay with the Blues.
He added: 'Birmingham have had the chance for a long time to leave an offer. They have left something, but it is not good enough.'
