Few players have troubled Pep Guardiola's Manchester City as much as Adama Traore has this season.
The winger scored both late goals in City's 2-0 home defeat to Wolves, before another goal and assist in the 3-2 defeat at Molineux over Christmas. If he hadn't played either game, City could have been four points better off in the Premier League.
The truth is, City couldn't handle Traore's raw pace in both fixtures against Wolves this season, and it's a credit to the 24-year-old for adding an end-product to his game over the last year to make that speed a real threat.
So it's no surprise to see reports linking City with making a summer move for Traore, along with Liverpool and Bayern Munich.
He is a player Guardiola admires, with the City manager telling broadcasters before the Molineux defeat it was 'impossible' to stop him.
"He is a motorcycle! It's almost impossible. Nobody can handle this pace," Guardiola said, before Traore proved him right over the subsequent 90 minutes.
Guardiola doesn't offer praise to opposition players lightly, showing how much of an impression Traore has left at City.
And a summer move for the Spaniard would make sense, especially if Leroy Sane joins Bayern Munich. Traore has Premier League experience, and his return of four goals and seven assists this season is a record he could surely improve upon with a better quality of player around him at City.
Traore began his footballing education at Barcelona, coming through the La Masia academy when Guardiola was manager of the senior team. His time developing under Nuno Espirito Santo at Wolves would also bode well for Traore if he did make the move to City. On paper - and on the pitch - he seems to tick plenty of boxes Guardiola would want from a new winger.
But apart from his attributes, signing Traore would be using a transfer tactic that City have successfully deployed in the past - strengthening themselves while weakening an opponent.
They signed Scott Sinclair from Swansea the summer after losing 1-0 at the Liberty Stadium and haven't lost against the Swans since. Signing Wilfried Bony in 2015 will have helped that record.
City had lost to Aston Villa twice in the seven meetings before signing Fabian Delph and are unbeaten since. Before Jack Rodwell moved to the Etihad, he had helped Everton to win four of their last five meetings with City. After they signed Rodwell, City won three of the next four clashes with the Toffees, before he left to join Sunderland.
Even in the current squad, Riyad Mahrez's transfer from Leicester has improved City's fortunes against the Foxes. Mahrez had helped Leicester to two wins and a draw over City, plus a League Cup draw in normal time before they lost to Guardiola's men on penalties. Against Leicester, Mahrez and City have won three of four meetings since.
So if Traore was to leave Wolves, they would not only lose one of the Premier League's most unique attacking threats, they could lose their main weapon in beating City.
Guardiola wouldn't just be getting a replacement for Sane, he could also be signing the key to win back four points that City lost this season.
