Aubameyang struck seven minutes before the break to ensure the 68-year-old Frenchman signed off his 22-year reign with a win in his 1,235th and final game in charge.
Arsene Wenger last night taunted Spurs by claiming they might have to sell Harry Kane to help pay for their new stadium.
"I believe I had an impact on the club as a whole because the club is in a strong position, it has a new stadium, a new training ground and new players", Wenger said on Sunday.
Adjudged as the last line of defence, the Greek centre-back left little option for the referee when he willingly felled Kelechi Iheanacho who was racing through on goal.
Looking back, unfortunately, in my job, you remember much more defeats than victories and so I have as well some painful memories. I don't know where is London.
"It has changed me a lot - it is hard to understand, when you don't live in this country, how deep the love is for the game". Richarlison admits to reading rumours linking him with United and Chelsea - and he has had plenty of time on his hands with his drop in form in the new year seeing boss Javier Gracia start him in just one of Watford's last six games. It's hard certainly. I came to London when I was 46 and for 22 years, this club was my life, the players and staff my family, the fans and press, I saw as well as friends... most of the time, I must say.
"Belgium is a good championship, play a year there". I thought maybe we won't score the second goal, but we can not concede - they never crossed the halfway line.
"We are going to see what happens in that regard".
However, it is certainly guaranteed that the stadium will be a noisy one, and both sets of fans will want to see their team end the season on a high.
"We have gone through a season of ups and downs but they have always created something special and I would like that to come out in the last game by the way we play it". A £10 million player when we built the stadium was huge. Nketiah has that quality to score goals and overall I think he might get a chance very early.
