Manchester United, Liverpool and Chelsea watched Sampdoria striker Patrik Schick in action on Monday night, a source has told ESPN FC.
Schick enhanced his reputation with a goal in Samp's shock 2-1 win over Inter Milan at the San Siro to take his tally for the season to eight.
The 21-year-old, who joined Sampdoria from Sparta Prague last summer, has played for Czech Republic at all youth levels and made his senior international debut last May. He has won three caps and scored one goal so far for his country.
Inter Milan and Borussia Dortmund are also admirers of Schick, but the Premier League trio are ready to battle for the forward this summer as they look to bolster their attacking options.
Schick still has three years to run on his contract at the Stadio Luigi Ferraris, but Sampdoria are bracing themselves for offers for the player this summer with the striker reported to have a £21 million buy-out clause in his contract.
