I think bringing him back would be the best piece of business the club can do for a number of reasons:
1. He wants to come back, and his affection for the club is evident.
2. He's not that valuable for Tottenham, and they would be willing to replace him. I believe they would accept an offer worth £40-50m, so we can actually make a small profit.
3. There's almost no risk involved. We know exactly what we are getting.
4. He improves us right off the bat.
5. Hard working player, the type Dyche appreciates.
6. It's a love story. Commercially, his return will generate a big chunk of the transfer fee paid.
7. He loves the club, and he is worth more to us than anyone else. We need more players like him.
