Southampton boss Claude Puel once came to blows with Arsenal rival Arsene Wenger.
The Mirror says Puel once left Wenger in a pile on the floor after a nasty training-ground tackle – and now he wants to inflict more pain on his mentor.
Southampton manager Puel was a tough midfielder in boss Wenger 's famed Monaco side, which won the French title in 1987-88.
But after being dropped for a few games, he took his revenge on Wenger with a wild lunge in a practice game which left the Gunners legend in a heap.
And the Frenchman wants to hurt his teacher from the Emirates Stadium's dugouts on Saturday.
