Jermaine Jenas believes Mauricio Pochettino 'crossed the line' by deciding to become Chelsea manager after previously managing Tottenham.
The two London rivals will meet for a fierce derby clash at Spurs later tonight, marking Pochettino's first match at his former employer with Chelsea.
Pochettino was named Graham Potter's permanent successor at Stamford Bridge in the summer, a decision that Jenas believes was wrong for the Argentinian to do given his previous ties at Tottenham.
Jenas enjoyed plenty of movement during his playing career and featured for five different English clubs, making over 200 appearances for Tottenham during that time.
