Brentford have ramped up their interest in signing forward Mykhaylo Mudryk and could hijack a move by Arsenal on the final day before the transfer window closes.
However, Thomas Frank faces competition from not just across London for the talented 21-year-old, with clubs across Europe interested in his signature. If the Bees meet Shakhtar Donetsk's rumoured asking price of at least £25m it would be a club transfer record after paying £17.1m for winger Keane Lewis-Potter earlier this summer.
It is not the first time Brentford have moved in for the Ukrainian, who can play across the forward line, after having an offer rejected last winter.
