Willian’s goal was his first since he joined from Chelsea on a free transfer last summer and came in his 37th appearance for the club.
The 32-year-old has come under fire for his performances and he admitted it has been a tough first year for him at Emirates Stadium.
“It was difficult, I am the first to admit that,” he said. “When I don’t play well, I am the first to criticise. Me and my family know how difficult it was for me this season.
“But I never doubt what I can bring to this team — my quality, what I can do — and I finally scored this beautiful goal. Let’s keeping going!
“[We scored] three fantastic goals and I am really happy with the performance and with the goal that I scored.”
After missing out on reaching the Europa League Final last week, this was a rather flat affair.
Mikel Arteta’s side remain ninth in the Premier League and any hope of qualifying for Europe looks a tall order given Spurs, in seventh, are four points ahead of them with three games to go.
Their youngsters, as has been the case all season, still excelled and it was fitting that Bukayo Saka and Smith Rowe combined for the opening goal. The strike was 20-year-old Smith Rowe’s first Premier League goal.
When asked about Smith Rowe, Willian said: “He is a fantastic player and I think he has a great future. He has technique and everything to become one of the best players in the League and I am happy for him.”
Saka was named man of the match last night and, while Arsenal’s remaining games may feel like a series of dead rubbers, the 19-year-old is keen to take full advantage of them.
He is trying to nail down a spot in Gareth Southgate’s England squad for this summer’s Euros and, by excelling at left-back yesterday, he highlighted his versatility.
Arsenal boss Arteta said: “He’s a kid who has the intelligence to understand different positions.
“He still has things to learn, obviously defensively, because it’s been a while since he played in that position, but I think he had the right approach to it. That’s the first and most important thing. And then his quality defines a lot of moments.”
