The Celtic striker is in footballing limbo at Lierse after being demoted to the reserves following criticism of manager Stanley Menzo in two outspoken interviews last month.
Celtic manager Neil Lennon was particularly concerned that Watt had alleged Menzo had slapped him in a row over headphones. And, Belgian League runners-up Zulte-Waregem and KV Oostende both confirmed they want to sign Watt.
Watt hasn’t featured for Lierse for six weeks now and Radzinski has little in the way of sympathy for the Scotland Under 21 international.
He said: “Tony shot himself in the foot.
“When you start criticising the manager, you damage the whole club.”
Watt netted seven goals in a four-game spell earlier this year before his bust-up with Menzo.
