NTwins, Janssen, Sissoko joined before Hitchen returned to the club.
In terms of cost and if they were a success:
Sanchez - £40m - Club record signing when he joined. Excellent first season, has not pushed on since. Important member on the first team squad. Unlikely to get our money back if we sold right now. Can we hold that against the scout?
Gazzaniga - Undisclosed - 22 appearances for us since joining and 1 international cap. I've never been a fan but I remember you calling for him to be first choice in the past. We'd probably make a profit if we sold.
Foyth - £11.7m - 16 first team appearances for Spurs and 10 international caps since joining. It hasn't turned out how we would have wanted and doesn't look like he's wanted by the current manager. There appears to be interest in him from other clubs and we might make a marginal profit on him.
Aurier - £22.5m - 58 first team appearances since joining. It looks like he has lost his first place position to Doherty this summer. He's a mixed bag, can be effective going forward but prone to mistakes. Improved under Mourinho. We are unlikely to make a profit on him if we sold.
Llorente - £13.59m - 36 appearances over two seasons. Leaving on a free transfer last summer. A useful squad player but limited how we could play. Played an important part in last season's CL run.
Moura - £25.56m - 74 appearances in the two and a half years he's been with us. A key player in our CL run last season. A key player for Mourinho.
Ndombele - £54m - Club record signing. Disappointing first season. Was in high demand when we signed him.
Lo Celso - £28.8m - 14 appearances last season, cementing his place in the first team after Christmas. Looks like a good signing and we'd make a profit if we were to sell.
Sessegnon - £24.3m - Peripheral figure in his first season. Yet to settle in a position. Still only 20.
Clarke - £9.9m - spent last season on loan and doesn't look likely to be in the squad this season.
Fernandes - loan - 7 appearances since joining in January. I think that he was probably bought in as cover following Sissoko's injury. A crazy £50m sale fee in his loan agreement.
Bergwijn - £27m - 15 appearances since January and would have been more if he hadn't got injured. Made an instant impact.
