James and Nzonzi would be a waste of money. James at 10 will not be a massive improvement on Ozil and or Iwobi. Btw, I'm typically not one for improving from within, but I want to see more of Iwobi. The kid has incredible vision and hunger. After Sanchez and a mentally fit Ozil, he gives me the most joy when I watch this Arsenal team. Just keep playing him.
Ozil needs to step up. He needs to be the playmaker he was last year and feed the 3 striker forward line.
Ramsey needs to come in and do a job with Cazorla injured and El Neny in the AfCon
Welbeck can come in and give us the workrate that's sometimes missing in the front line apart from Sanchez
And Lucas still has a lot more in store.
Trades are not the only way to improve a team. We have to exploit what we have, including the manager improving tactics and substitions. You can't just throw money every time you're unhappy
