Boro are keen to sign at least one more centre-back before the start of the campaign, yet there is also a lack of creativity in the final third.
We’ve picked out nine creative players who could be available for Boro to sign on loan this summer – scroll down and flick through our gallery to see them:
5. Sheyi Ojo (Liverpool)
The versatile playmaker was in and out of the side during a loan spell at Rangers last season. Ojo has three years left on his contract at Liverpool but doesn't look like breaking into the first team, so his next move is unclear. Photo: Andrew Powell
6. Anthony Gordon (Everton)
A teenager who is highly rated at Everton and made 11 Premier League appearances at the end of last season. Yet at 19, the Toffees will probably feel he needs more regular game time to help his development. Photo: CLIVE BRUNSKILL
7. Tariq Uwakwe (Chelsea)
The Blues are reportedly prepared to allow Uwakwe to head out on loan while the likes of Swansea and Derby have previously been linked with him. The 20-year-old played for Chelsea's under-23 side last season. Photo: James Chance
8. Luke Freeman (Sheffield United)
After signing for the Blades last summer, the 28-year-old has made just 11 Premier League appearances and four league starts. He will be keen to get his career back on track this season, whether that is at his current club or elsewhere. Photo: Shaun Botterill
