According to The Pitch Prospect, Celtic have made an initial inquiry for West Ham striker Callum Wilson.
Any move is expected to be contingent on Wilson becoming a free agent and talks over an exit from the Hammers are ongoing.

It is believed Wilson wants to leave the London Stadium, but Celtic want to understand Wilson’s interest in playing in Scotland and his salary expectations before expressing any interest.
The Glasgow side are looking for several attackers this winter and have also inquired about Chelsea striker David Datro Fofana.
Fofana is currently on loan at Turkish club Fatih Karagumrük, where he scored seven goals in 14 appearances.
Celtic’s striker options have been exhausted following an injury to Callum Osmand.
The summer signing has been out since November with a thigh injury and has missed the last 16 games.
Fellow center forwards Kelechi Iheanacho, Shin Yamada and Johnny Kenny have only scored eight goals between them this season.
Wednesday’s win over Falkirk leaves Celtic six points behind leaders Hearts and level on points with Rangers.
Burnley and Leicester are also aware of Wilson’s situation, while Saudi clubs Al Ettifaq and Al Shabab both considered signing the former Newcastle striker before he moved to West Ham.
The 33-year-old moved to the London Stadium in August after becoming a free agent following his departure from the Magpies at the end of last season.
Upon his arrival, Wilson signed a one-year contract that expires this summer.

Since then he has played 17 Premier League games and scored four goals.
However, the last of these encounters took place in November against former club Bournemouth.
Wilson, who scored two goals in nine appearances for the England national team, has since failed to score in his last eight league games for the Hammers.
Meanwhile, he was left out of the matchday squad for the home defeat to Nottingham Forest on 6 January.
The striker was again absent from last weekend’s FA Cup third round win over QPR.
This came after Nuno Espirito Santo added two new strikers to his squad at the start of the transfer window.

Taty Castellanos and Pablo both joined the club this month for a combined £47million.
However, Niclas Fullkrug moved to AC Milan on loan, while youngster Callum Marshall moved to German club Bochum until the end of the season.
