Arsenal manager Unai Emery has said the team will only sign players who would "really improve" his squad amid rumours the club could make another last-ditch move for Celtic left-back Kieran Tierney.
The Premier League transfer window will close on Thursday evening. Emery spoke to reporters following Sunday's 2-1 defeat to Barcelona in the Joan Gamper Trophy and suggested Arsenal's business may already be concluded, per Goal's Chris Burton:
"It has not changed, our idea and our message. Only if we can sign a player who really, really can improve our squad, then we are going to do that.
