The Red Devils are confident of signing England global Danny Rose either in the new year or at the end of the current campaign, as per claims.
Manchester United will look to top Group A, with at least a point against CSKA Moscow at Old Trafford on Tuesday evening and will go through barring a seven goal defeat to the Russian outfit.
Rose established himself as England's first-choice left-back thanks to his impressive performances in the Tottenham team under Pochettino.
It's been suggested that if Danny Rose were to depart without a direct replacement at the club, Pochettino would pursue Celtic's Kieran Tierney when the market recommences in January.
The 27-year-old is valued at £45m by the Lilywhites whose move into the new White Hart Lane next season is now under threat due to escalating costs.
Reports in the press now claim that Mourinho is determined to get Rose on board, and although negotiations with Spurs will be hard, expects to and him in a £50million deal.
This led to speculation linking him with a switch to United but Spurs refused to sell Rose after already losing Kyle Walker to Manchester City so the player ended up staying after issuing a public apology.
However, the Doncaster-born England worldwide will find a move to Old Trafford hard to resist, particularly with the 2018 World Cup finals at the forefront of every player's mind.
