Celtic continued their pursuit of Aleksandar Tonev at the weekend by sending a scout to watch him play for Lech Poznan.

The Bulgarian helped Lech to a 1-0 win against Wisla Krakow to send his side top of the Polish League.

Lech are resigned to losing the player in the summer, with a price in the region of £2m believed to secure the player.

However, Celtic will have competition as scouts from Roma also watched Tonev, who has been linked with a string of Serie A clubs.

Tonev said last week that he wouldn't make any decision on his future until after the Polish League title has been decided.

He said: "I am a professional and my job is to do the best I can for my club. There is no point in thinking about a transfer to right now. I just want to keep playing well."

Tonev has two years left on his deal in Poland. Neil Lennon, the Celtic manager, has stressed the need to bring in players next season and Tonev is high on his wanted list.
