I load some images in a QLabel, I want to get it to detect the right click of the mouse and I throw the coordinates

from PyQt5.QtGui import *
import sys
import copy
sys.path.append('../')
class Ui_MainWindow(object):

    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(790, 570)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.lblTablero = QtWidgets.QLabel(self.centralwidget)
        self.lblTablero.setGeometry(QtCore.QRect(0, 0, 790, 550))
        self.lblTablero.setText("")
        self.lblTablero.setObjectName("lblTablero")

        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 802, 21))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)
    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))


if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    Tablero = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(Tablero)

Try it:

#import copy
#sys.path.append('../')

        self.centralwidget.setObjectName("centralwidget")
        #self.lblTablero = QtWidgets.QLabel(self.centralwidget)
        self.lblTablero = CustomLabel(self.centralwidget)          # +++
        #self.lblTablero.setGeometry(QtCore.QRect(0, 0, 790, 550))
        self.lblTablero.setText("lblTablero")
        self.lblTablero.setObjectName("lblTablero")
