A former football agent slashed his estranged wife's sofa with a kitchen knife because he thought she loved it more than him, a court heard.
Peter Harrison, 57, ignored a police warning to stay away from his wife Wendy when he pushed his way into her Gateshead home last July.
Harrison, the ex-agent of England striker Andy Carroll, admitted harassment at Newcastle Crown Court.
He was sentenced to nine months custody suspended for 18 months.
Harrison, who was dropped by the England striker just before his £35m move to Liverpool from Newcastle in 2011, was also ordered to carry out 175 hours of community service and pay court costs of £490.
