Much of the recent transfer speculation has centred on Michael Essien, but tying Mahamadou Diarra to a new contract should be new Lyon Coach Gérard Houllier’s top priority.
Few would dispute the idea that the Ligue 1’s best performer in 2004/05 should be selected from the Lyon side.
Alexander Frei (20 goals) has been exceptional for Rennes and Bonaventure Kalou has provided moments of true footballing beauty with Auxerre, but the fact is the champions have been head and shoulders above the rest this season.
Cris, in his first year, has been a rock at the back, Grégory Coupet is now surely France’s best goalkeeper and Sylvain Wiltord is enjoying a fine renaissance.
It is the midfield three, ‘le triangle d’or’, of Juninho Pernambucano, Essien and Diarra that sets this Lyon team apart, however.
While Essien, at 22, has the potential to become one of Europe’s finest players, Diarra and Juninho are already at the top of their games and have this year emerged as Lyon’s most influential players. The hard-working Brazilian can put in a strong claim for the award on the back of his free kicks alone - particularly the ridiculously good 35-yard effort that bent like a banana and effectively ended Werder Bremen’s Champions’ League hopes.
But Diarra’s all-round contribution has simply been immense. Sitting in front of the back four, it is the 24-year-old Malian who pulls the strings for the four-times champions. It is he who decides how far up the pitch Lyon play, it is he who invariably breaks up the opposition attacks and it is he who moves the team forward – with a short pass to Juninho on his left or to Essien on his right, or with one of those long, raking balls for Govou, Wiltord or Florent Malouda that he has mastered in true David Beckham style.
And lest we forget, moments before Juninho’s Weserstadion heroics, Diarra had rifled Lyon into a 2-0 lead with a quite stunning goal of his own.
‘Djilla’ as he is known by his teammates, is also a much-liked figure in the dressing room. "A class player who basically does it all," is left-back Eric Abidal's summation. “He wins the ball in the air from goal kicks, he makes the crunch tackle when there’s danger and he’s always there when we need an option."
“We’re lucky to have him,” adds Cris. “His attitude is fundamental to the team - he never, ever gives up.” Or as Juninho himself puts it: “Quite simply, when you watch Lyon play, you realise pretty quickly that he is the boss.”
Worryingly for Lyon fans - and whisper this quietly - Diarra’s current contract gives him the option to leave Lyon for a cut-price figure, believed to be around £5m. Arsenal boss Arsène Wenger is ready to pounce, but Jean-Michel Aulas, the Lyon President, is prepared splash out on a lucrative new deal to keep the Mali captain, who has won three straight titles since arriving from Vitesse Arnhem.
Certainly Houllier, who admitted to being "aware of the economic realities” following his appointment on Sunday, will not want to lose any of his players this summer. But while the blow of Essien leaving would most probably be softened by a sweetener of around £20m, losing Diarra could prove a much harder pill to swallow.
