Mikel Arteta was handed a major boost ahead of Arsenal's Champions League clash with Paris Saint-Germain on Monday with Mikel Merino fit enough to train, likely clarifying the shape of the starting XI that will take to the field in the semifinal first leg on Tuesday night.

Merino missed the Gunners’ most recent match - against Crystal Palace last Wednesday - and was a doubt for the first leg of Arsenal’s semi-final against PSG at Emirates Stadium on Tuesday. But the Spaniard took part in training on Monday afternoon and is fit for the game.
