The last week has seen Manchester United, as ever, linked with an abundance of transfer targets. One who has come to the fore is Marco Reus - the German international at Borussia Dortmund.
The attacker, who has a release clause that becomes active in 2015, has been linked with United as well as Barcelona in recent weeks - and he is in tremendous form once again.
Yesterday he bagged a goal and an assist in the game - following on from his performance against Bayern Munich a week ago and VfL Wolfsburg in midweek.
Unfortunately Reus also has a reputation for being a fierce competitor and that showed against Wolfsburg in midweek - as he got involved in a 30-yard slanging match with his own goalkeeper Roman Weidenfeller.
That was described as a non-event by the BVB boss Jurgen Klopp - but he is facing similar questions this week - as Reus this time got involved with Robert Lewandowksi.
The Pole, who is level in the goalscoring charts with future Bayern Munich team-mate Mario Mandzukic, wanted to take a 79th minute penalty with the score already at 3-2 in order to gain the advantage over the Croatian.
But Reus is the regular penalty taker and he was not about to abandon his station.
Bild state that Lewandowski was unhappy with Reus after being told to step away - and he looked it, visibly sulking on the edge of the box as Reus slotted away from 12 yards.
BVB general manager Michael Zorc said of the incident:
"I do not know if it has crackled there. Sure, Robert would have liked to shoot. But we have a first-choice taker who has the right to shoot. "
Lewandowski did not speak to journalists after the game while Reus skirted the issue by only talking about the team’s current form,
But any hope that this rift could help United sign him is of course erroneous - as Lewandowski is on his way out.
But it again shows just how much of a fierce and committed player Reus is.
