Bruno Fernandes transformed Manchester United when he arrived last January.
The Portuguese midfielder has been simply unplayable at times, scoring 14 goals and providing 10 assists in his first 26 games for the club.
Impressive stats are far from his only contribution though.
Since joining United, Fernandes has helped completely transform Ole Gunnar Solskjaer's side.
It's clear he's a true leader on the pitch as well as in the dressing room and he was one of the main driving forces behind the club's unlikely top-four finish last season.
But, if the latest reports are to be believed, his time in Manchester could be short-lived.
According to The Sun, Barcelona and Real Madrid are ready to 'lock horns' in a transfer battle to sign Fernandes.
Both Spanish giants are closely monitoring the player's situation and will fight to get him out of Old Trafford just eight months after he arrived.
No doubt that'll be worrying news for Man United fans. The pull of either Barca or Madrid - let alone both - would be almost impossible for any footballer to turn down.
It's also interesting these links have emerged so soon after a number of reports suggested that Fernandes is already losing faith in Solskjaer.
While the midfielder has denied there are any serious problems at the club, he was upset about being subbed off at half-time during Man United's 6-1 humiliation against Spurs.
He was also very vocal in the dressing room that day, apparently criticising his teammates and the manager's tactics.
Those reports have no doubt sparked the interest from Spain's two top clubs and it will be interesting to see how the situation develops.
It would be shocking to see Fernandes leave Man United after just 12 months, but if Real Madrid and Barcelona really do come knocking, then Solskjaer will have a big problem.
