Tottenham boss Mauricio Pochettino is keen on Celta Vigo midfielder Stanislav Lobotka, according to the Daily Mirror.
Lobotka, 23, is a Slovakia international and only signed a new deal in February which runs until the summer of 2023.
But the Mirror say he has a £31m release clause and is keen to move on this summer.
Meanwhile, West Ham are reportedly moving closer to signing Lucas Perez from Arsenal.
The 29-year-old Spaniard has struggled to establish himself in north London and was sent to Deportivo La Coruna for a loan spell last season.
The Sun have picked up on reports suggesting that Perez’s move to West Ham could be completed on Monday.
West Ham have made a £10m offer for Le Havre’s 20-year-old French centre-back Harold Moukoudi, the Daily Mail say.
Leicester have had a £10m bid for Brentford defender Chris Mepham rejected, also according to the Mail.
The Times say Fulham have made an approach for Celtic’s former Manchester City defender Dedryck Boyata.
The Times also reports that Chelsea will let Thibaut Courtois go if he tells the club he wants to leave.
The story is based on Courtois’ agent publicly urging Chelsea to let Courtois move to Real Madrid and Blues boss Maurizio Sarri responding by saying he wants to speak to the goalkeeper in person.
Sarri said: “I am not interested in the agent. I want to hear if Courtois will say to me the same.
“I have to speak to my club of course. I want only players who have a very high level of motivation.”
