Unai Emery has defended his decision to remove Lucas Torreira at halftime, noting both the game's environment and a possible injury worry.
“I decided to do the change of Lucas Torreira because after the red card, the atmosphere is against him and also the doctor said to me in the first half that he has a little pain for Thursday and I decided okay, it's the moment [to take him off],” Emery said following Arsenal's 1-0 win over Watford.
Torreira of course was the subject to Troy Deeney's elbow that earned Deeney a red card. The holding midfielder had a couple of fouls of his own, with the Watford supporters baying to the referee “off, off, off” asking for a red card. Emery may have felt that as the game went on, Torreira could go hard into a challenge and come out with a red card, and Arsenal needs Torreira healthy and active for future Premier League matches.
On the field, it didn't seem that Torreira had an injury, but ahead of Arsenal's crucial return leg against Napoli on Thursday, Emery appears to have decided it was better not to risk Torreira in the second half and instead play with Mesut Ozil in a more attacking formation. That way, Torreira should be good to go at Napoli. Ultimately, the move paid off, with Arsenal holding on to the 1-0 victory.
Since joining in July, Torreira has been a revelation, emerging as the holding midfielder that Arsenal has been missing for a decade or more. When healthy and in form, Torreira eats up opposition attacks, cutting down space all over the field. He's even scored a goal or two, as seen in one of the North London derbies earlier this year.
