Matías Viña - Palmeiras: Palmeiras’ Matias Vina is a South American LB whose metrics and availability make him a potential choice for Arsenal to bring into their club for the summer window. Despite playing in a gung ho side, the 23-year-old isn’t an erratic LB, and he provides stability when Palmeiras are under pressure from the opposition. In the final third, he holds his own by having the strength to power past the opposition RB, he can invert as an LDM if Arsenal does want to play a 4-3-3, and he performs best when more centrally. For Arsenal, that means they can play Nicolas Pepe as an LW and the synergy between both players will be more than good enough to seamlessly transition between Tierney and the backup LB.He has some faults, his concentration levels dip at random times, with Palmeiras conceding unnecessary goals because of it, but Vina isn’t that bad as an individual player. For the right price tag, he could be a good backup to Tierney for Arsenal to secure.Felipe Jonatan - Santos: He’s someone I’m not keen on because of the flaws he possesses. He overhits the ball when dribbling, he doesn’t attack from the outside (he prefers to camp right outside the box when his team attacks,) and he’s too nimble and weak to be a PL level LB. Felipe also gets caught ball-watching too often, despite being the only left-sided Santos Player that’s there just to provide the width for his side.He’s a decent final third attacker (even with his tendencies to drift inwards,) he can hold down his flank and he won’t get swept aside 1v1 against better/faster wingers. However, he isn’t the LB that Arsenal should look to get in to deputise for Kieran Tierney as the quality drop off would be too much to bear for Arsenal.Vitaliy Mykolenko - Dynamo Kyiv - He’s a risk-averse LB with generally good positioning when his team are settled in possession. His tackling is strong, and the power he generates makes it hard for opposing players to play through him when he’s on the floor, which is also helped by his strong recovery pace when his tackles are mistimed/weakly done. He can attack both on the inside and outside with his crosses being of a good standard.He’s a rash player that can switch off/lose intensity over a 90-minute game, that itself isn’t a bad trait for a player to possess, but for a team like Arsenal, consistency is what their LB needs. He can develop consistency with Kieran Tierney being his rival in the position, that isn’t an issue and Mykolenko is a good option to have at LB. Although he has the same issue as Wijndal, there are good teams in for him that would offer him a guaranteed starting 11 role, so convincing him to deputise for Tierney would be difficult to do.Josh Doig - Hibernian: Hibernian’s Josh Doig is available for £5m this summer, which is a good deal on paper for any club looking at LB’s. He’s 6’3, he can operate both as an inverted fullback and as a traditional one, his ball-striking on both feet is to be desired & he can impose himself on the final third if needed be.
