We need more pace, so a quick forward who can play anywhere across the front 3. A right back to replace Seamus can wait until the summer.
I'd take Erisken over Alli personally, especially as you already have James there. He's available. Conte doesn't like him and Eriksen knows he's not wanted. They'd loan him initially for a sale later.
I’d not want us to commit to buy tbh. The lad needs a move and has plenty to prove, as well as trying to get his England place back, but he’d be a massive gamble on a permanent deal imo. If he came on loan and proved himself then fair enough.
