Don't change a winning side is what they say. Adding depth to the squad is never a bad idea though. With just the Premier League and Europa League left the equation is straightforward for Arsenal.
They have added three new bodies to their squad and seen two peripheral figures move on loan for the rest of the season too. Although the injury to Mohamed Elneny leaves them down a midfielder for now it's hard to argue that they haven't improved over the January window.
It may not have been the reinforcement that many wanted but the winter is rarely a time for major changes. Manchester City's recent title wins have come without huge additions whilst Liverpool buying Luiz Diaz last year was closer to a Leandro Trossard type signing than it was a marquee entry.
