With Alexandre Lacazette a doubt for Arsenal's Premier League trip to Southampton on Saturday, manager Mikel Arteta could give summer signing Mika Biereth his debut for the London club.

Lacazette has been a regular feature during Arsenal's top four push, though the former Lyon man hasn't had his most prolific season. And, with football.london reporting that the Frenchman missed training ahead of the game at St Mary's, Biereth could be involved.

With Kieran Tierney alread expected to miss the rest of the season, and Arteta confirming Thomas Partey will be out for a number of weeks, Arsenal's squad is already looking thin. The manager has already been forced to call on youth this season, and summer arrival Biereth may need to step up.

Biereth joined Arsenal from Fulham over the summer, having scored 21 times in the under-18 Premier League last term. This season, the Dane has 10 goals for Arsenal's under-23s in Premier League 2 this term, including two against Manchester City in his last appearance, but has yet to make his senior bow.

“It’s a once in a lifetime opportunity and I couldn’t really turn it down," Biereth told Arsenal.com upon signing for the club in July. "I think now with the recent track record of youth going into the first team, I thought it was a great project to try and be a part of.”

Arteta has included the 19-year-old in a matchday squad just four times
