Bordeaux coach Gus Poyet admits he's upset losing Malcom this summer.
The Brazilian winger is in talks with AS Roma and Barcelona this week, with Bordeaux willing to sell.
Poyet lamented: "If it helps to unblock the situation (at the level of arrivals) ... We must also know that we talk about our best player. He was our top scorer, the one who made the most assists, differences.
"If he leaves, the team will feel it. We have already felt in the friendly against Berlin (1-1, without the Brazilian). The first-half was beautiful but something was missing. You can call it Malcom or quality (laugh). And that's why we did not win the match."
