It could represent an excellent piece of business by Arteta, with Trossard already a proven Premier League player, he will need no time to settle in and could hit the ground running against Manchester United on Sunday.
The Spaniard won't be stopping there however, as he aims to add perhaps another attacking option to his squad ahead of what is a crucial few months ahead in the title race.
The 40-year-old could well return for summer target Yeremy Pino according to journalist Dean Jones, who spoke to Football FanCast regarding the Gunners' interest in the Villarreal winger:
“Yeremy Pino, a player they have explored previously, could certainly be considered as a backup that they might return to.”
Pino could be a terrific Mudryk alternative, especially due to his versatility which has seen him play on both wings this season as well as through the middle on a few occasions.
Last season, the 20-year-old sensation burst onto the scene, scoring seven goals and registering four assists while his attacking talents were on display across his 31 LaLiga appearances for the Yellow Submarine.
The £50k-per-week winger created six big chances while also making 0.6 key passes per match and could have added to his goal tally had he not missed five big chances too.
Talent scout Jacek Kulig has previously lauded the youngster, describing him as “incredible” and Arteta could take his development to the next level should he manage to lure him to England.
There is no guarantee he would be a starter initially, especially with the form that Bukayo Sako and Gabriel Martinelli have been in this season – registering 13 and nine goal contributions respectively – but with a buzz about the Emirates for the first time in a good while and a clear direction of where the team is going, Pino could eventually establish himself in the starting XI.
The Spanish wizard - who is thought to be valued by the Yellow Submarines at around €50m (£44m) - would jump at the chance to show his potential in the Champions League once again having scored in the competition for Villarreal last year and with Arsenal edging closer to glory, Pino could become part of a new generation.
