Marek Cech's agent is claiming the West Brom defender is wanted by his former boss, Tony Mowbray, at Celtic. Juraj Venglos told SITA: "I can confirm that Twente would very much like to capture Marek.
"Apart from the Dutch club, Celtic are also maintaining their strong interest.
"But the problem is that West Brom do not want to release him. Di Matteo counts on him as a member of his squad for the upcoming season."
Venglos expects a decision on Cech's future before Sunday, adding:
"I believe that everything will be sorted properly within this week.
"It is also possible that Marek will spend another season at West Brom."
