With Ole Gunnar Solskjaer set to lead Manchester United on a summer spending spree after being installed as the permanent boss at Old Trafford, the club's earnings from sponsorship deals could prove more than useful.
United may have fallen off the pace set by local rivals Manchester City in recent seasons, but the Red Devils continue to lead the way in terms of global stature. Their €71.1m ($80m) per season shirt sponsorship deal with Chevrolet remains the biggest deal of its kind in Europe.
Here is a list of the top 20 shirt sponsorship deals around the continent.

Betting companies have become a high-trending source of shirt sponsorship in recent times, and West Ham are the club to benefit most from the industry's investment in kit deals.
