Why Leandro Trossard, Arsenal's two-footed finisher and big-game specialist？

It was quite something to witness the explosion of celebration that greeted Leandro Trossard's equaliser for Arsenal against Bayern Munich from the press box at the Emirates Stadium.

With his sweeping, first-time finish, following nimble footwork by fellow substitute Gabriel Jesus, the Belgian nearly took the roof off the place. He is making a habit of scoring crucial goals.

The latest of them called to mind the words of his former coach at Genk. "He can handle any situation," Michel Ribeiro told Sky Sports last year. "The goals he scores, they are not just against small teams. He always scores against big teams and world-class defenders."

Bayern's defenders can testify to that. So too can Porto's after the goal that set up Arsenal's shootout win in the previous round of the Champions League. Trossard's overall tally of 13 goals this season includes strikes against Manchester City, Chelsea and Liverpool too.

It is worth considering the context they came in.

His strike against City, in the 11th minute of stoppage time in the Community Shield, again allowed Arsenal to win on penalties. His goal against Chelsea clinched a point at Stamford Bridge. Against Liverpool, it was a late solo effort to seal a 3-1 victory. There was a winner away to Everton in September too.

Trossard's appetite for the big occasions was also clear during his recent return to former club Brighton, where he silenced the jeers of the home fans with a beautifully-taken third Arsenal goal.

His knack for troubling top opposition predates his move to Arsenal. Consider the fact that the final goals of his Brighton career came against Chelsea, Manchester City and in the form of a sensational hat-trick in a 3-3 draw with Liverpool at Anfield.
