Arsenal would make a good choice by signing Arthur and Tielemans both. But I believe that they should be focusing on signing especially Tielemans. Because Tielemans' performance at Leicester has been very fascinating until now. He has already drawn the attention of big clubs undoubtedly. Considering this point, Arsenal would make a great addition if they sign him. And as for Arthur, I haven't liked him so far. And I don't know if he can start playing better in case he comes to Arsenal.
If the fund is available, yes they should get both of them. But do not forget that Arsenal is targeting this Brazilian Burno Guimaraes. Arsenal have identified Guimaraes as a potential addition this month with Mikel Arteta keen to improve his midfield options before the end of the window. So now Arthur Melo, Youri Tielemans and Bruno Guimaaraes. And they are all young players. It now looks like the deal for Bruno Guimaraes is proving difficult, so they should be expecting the one for Tielemans to equally take the same shape as I feel it would be difficult to sign a player of his caliber from another rival club like Leicester during a winter transfer window. If these two transfer does not go through then Arthur for me is also superb. Defensively he may not be what Arsenal needs but would be a great addition to Arteta's project. He's just a natural baller.
I've watched Tielemas performance at Leicester city and have known how good he is,but I don't know if Authur Melo will be a good addition or he will be a total flop at Arsenal just like some players are in the club after signing them for a huge amount of money.
Very soon,Arsenal will embark on a massive clear out to trim down the squad and leave only useful players at the club.
Tielemans has like 18 months left on his contract and I don’t know if he’d want to extent his contract at Leicester city. I feel so doubtful that Tielemans will go anywhere this month, with Leicester expected to keep hold of him until the end of the season as they look to convince him to sign a new deal. He’s a very good central midfielder and the fact that he’s been playing in the EPL for a long season now proves that he’ll balance up the Arsenal midfield. The problem is Edu, the Brazilian. He knows that Leicester won’t put a small money on him. They won’t even want deal with Arsenal either. For me, Arthur Melo is a good one considering the fact that he is a ball playing midfielder. That’s what completes a team’s midfield. It help keeps possession and reduces mistakes defensively. If we can’t buy any player at a heavy sum now, then Arthur should be the way.
