1. Ben Woodburn (Liverpool)
After bursting onto the scene in a World Cup qualifier with Wales in 2017, the youngster struggled during a loan spell at Sheffield United last season. Even so, the winger, 19, still possess plenty of pace and skill which could bolster Boro's options. Photo: Nick Taylor/Liverpool FC
2. Axel Tuanzebe (Manchester United)
Tuanzebe played a key part in Aston Villa's promotion to the Premier League last season, making 25 Championship appearances and starting all three play-off fixtures. The 21-year-old defender is predominately a centre-back but can play anywhere across the backline. Photo: Matthew Peters
3. Mason Holgate (Everton)
Despite missing a penalty in the Championship play-off semi-final for West Brom, Holgate impressed during his loan spell at the Hawthorns last season. The 22-year-old defender joined Everton in 2015 but looks unlikely to be a regular starter this season. Photo: Harry Trump
4. Lucas Piazon (Chelsea)
Now 25, the Brazilian winger struggled during a loan spell at Italian side Chievo last season. He did help Fulham win promotion to the Premier League in 2018 though, following his loan switch to Craven Cottage. Photo: Albert Perez
