Welbeck who will be out of contract next summer, is yet to start a league game this season, but now has four goals to his name for Arsenal.
However, the Hornets came out on top in the two meetings prior to that 3-0 defeat, and are priced at 6/1 (7.00) to pull off another shock win here. Meanwhile, Mesut Ozil and Pierre-Emerick Aubameyang have been rested completely by Emery.
"I want to look at him also with our best performance and for him to stay in first XI".
'I am very happy individually with the player, ' Emery said after the game. When he's playing with a performance like today, he's helping the team.
"We restricted them to a few chances, but never played at the intensity I really wanted in the first half".
However, Brentford gave themselves hope by reducing the deficit in the second half, with Alan Judge converting from a free kick in the 58th minute, guiding the ball over the wall and into the back of the net.
Emery was also questioned on Welbeck's contract situation, along with that of his team-mate Aaron Ramsey.
Each match is very important for the players, they can show us and show every supporter and every person their performance.
Former Chelsea FC striker Cascarino is impressed with the Arsenal manager's efforts to play the two strikers in his team. I am telling you, the performance and the commitment of the player is very high.
