The 28-year-old looks completely reinvigorated since he joined West Ham United in January.
In 11 appearances for the Hammers, Lingard has scored nine goals and provided four assists.
United are still undecided on what to do with their academy graduate.
The same can't be said about Lingard, with Eurosport reporting the England international thinks his time at Old Trafford is over.
West Ham are frontrunners to sign Lingard and want United to accelerate talks over a permanent deal.
They are waiting patiently to hear from the Red Devils about the potential costs.
