On Monday afternoon the Bees, who are three points above the relegation zone, replaced Sanchez with Martin Allen for the final three games of the season - a man the former Northern Ireland boss succeeded at Underhill upon his departure to take charge of Notts County at the end of last term.
"Following the termination of my contract by Barnet FC, I'd like to express my extreme disappointment at the lack of loyalty shown in me by the club," read a statement released by Sanchez. "It is the same lack of loyalty the club accused Martin Allen of showing when he walked out on Barnet towards the end of last season.
"When I took over from Martin, the club were three points adrift of safety with just four games of the season left and under serious threat of relegation to the Conference. However, thanks to a fantastic effort from the players, staff and myself, Barnet took seven points from those last four games and avoided relegation.
"Now, exactly a year since my appointment, the club are three points clear of the relegation zone with three games to go. I certainly felt that recent performances would see the club remain clear of the threat of relegation.
"Unfortunately, that confidence seems not to have been mirrored in the boardroom and I am disappointed the club have lost their nerve at such a vital stage of the season."
