Alexis Sanchez's superb solo strike was typical of the Arsenal star, Arsene Wenger beamed, after the Gunners won 2-0 at Southampton on Wednesday.
The Gunners ran out 2-0 winners at St Mary's; Sanchez and Olivier Giroud getting the goals to move Arsenal back fifth in the Premier League table.
Arsenal must now win their three remaining games and hope City or third-place Liverpool drop points if they are to secure a 20th successive season of Champions League football. It was a very convincing win. "It is hard to accept this game is lost - we need to find that clinical edge".
"The goal he scored tonight shows what he's about: very good technique in a short space". We know we can only win our games, and we had a strong performance on Sunday. And both of them have played well, and both of them have a great team spirit as well.
On Arsenal, Hughes continued: 'I've always liked going up against them.
After a boring first half at St. Mary's Stadium here on Wednesday, Sanchez received the ball in the area from Mesut Özil and blasted the ball past Saints goalkeeper Fraser Forster to put Arsenal 1-0 up in the 55th minute.
"Recently we shot ourselves in the foot against Tottenham, because we did not get any points and obviously we left ourselves in the situation where we have to keep winning every game", said Cech. "It is our last home game, our fans will be totally behind us and the fact that it is Arsenal will add to the mix, so I'm really looking forward to it".
"We were focused and I felt that when we suffered, we stuck together", Arsenal manager Wenger told the BBC.
'We need to be more potent, we are aware of that, and we would love to address that over the final two games.
None of the guests' last eight league away games have resulted in draws, but you can get odds of 16/5 (4.20) on them being forced to settle for a single point in this one.
It initially appeared that the closest chance of a Premier League play-off would take place between Liverpool and Manchester City if the pair ended up equal on points, goal difference and goals scored.
And it was the visitors who had the first real chance as Aaron Ramsey sent an effort wide before Arsenal's three-man defence conspired to play both Dusan Tadic and Gabbiadini onside, with the latter seeing an effort well saved by Petr Cech.
